Green Tea Or The Wonder Drug: From 1 Different Sources
Green tea is considered a “wonder drug” because of its healthy contribution in human diets. Its antioxidant properties fight successfully against cancer, but not only.
Green tea description
Green tea is made from Camellia sinensis, an Asian plant, originating from China, Japan and South Korea. Oolong tea and black tea are prepared from the same plant as the green tea. A special feature of this type of tea is the ability to block the natural process of fermentation: after being picked, its leaves are steamed, dried and then rolled, thus blocking fermentation.
Due to its constituents, it acts as an antioxidant, diuretic, cerebral and fattening burning stimulator, and also as a cancer protector.
Green tea has been the subject of many scientific and medical studies so as to determine its health benefits. It seems that regular green tea drinkers may have a lower risk of developing heart diseases and certain types of cancer.
There are several types of green tea available on the market: Bancha Tea,
Chun Hao Tea ,
Dao Ren Tea ,
Dragonwell Tea ,
Genmaicha Tea ,
Gunpowder ,
Gyokuro Tea ,
Hojicha Tea , Kai Hua Long Ding Tea,
Kukicha Tea ,
Matcha Tea ,
Sencha Tea , White Monkey Tea.
Green Tea brewing
To prepare
green tea, use
: two grams of tea per 100ml of water, or one teaspoon of green tea per five ounce cup.
Green tea steeping time varies from thirty seconds to two, three minutes. The temperature differs as well, from 140°F to 190°F.
Consumers recommend that lower-quality green teas to be steeped hotter and longer and higher-quality teas to be steeped cooler and shorter. In case of steeping the green tea too hot or too long, the resulting beverage is bitter and astringent.
Green Tea benefits
Green Tea lowers the risk of cancer.
Studies have shown the green tea’s contribution against tumors growth, due to its high content of antioxidants, able to fight free radicals which are responsible for cancer spreading.
Green Tea lowers the risk of stroke and heart diseases.
The formation of blood clots (or
thrombosis) is the main cause of the heart attacks and strokes. Green Tea has been acknowledged to exhibit abnormal blood clot formation.
Green Tea lowers blood pressure.
Green Tea is proven to block the effects of an enzyme secreted by the kidneys, considered to be one of the main causes of hypertension.
Green Tea prevents tooth decay.
Dental plaque and bacterial colonies that occur on the tooth surfaces and cause tooth decay can be inhibited by one of the compounds of the
green tea. Also, this beverage has been shown to be effective against fighting gum diseases.
Green Tea inhibits viruses
Studies revealed that
green tea can kill certain bacteria and staphs. It blocks the development of several viruses such as viral hepatitis.
Green tea has also been successful in:
- Slowing early aging;
- Diets;
- The treatment of physical or intellectual fatigue;
- Treating fast cold and flu recovery;
- Preventing allergenic reactions;
- Balancing body fluids;
- Improving the immune function of the epidermis;
- Preventing and mending arthritis;
- Improving bone structure
Green Tea side effects
Green tea is not recommended to patients suffering from high blood pressure, gastric acid secretion, gastritis and ulcer.
Due to the amount of caffeine contained, scientists advise a reduced consumption of green tea for pregnant and nursing women.
Also, this tea should not be drunk after 5 p.m., because the consumption may lead to insomnia, palpitations and agitation.
Green tea is a well known beverage, especially due to its medicinal contribution to a large array of diseases such as arthritis, heart diseases and several types of cancer.
A group of drugs used to treat high blood pressure (HYPERTENSION). Untreated hypertension leads to STROKE, heart attacks and heart failure. The high incidence of hypertension in western countries has led to intensive research to discover antihypertensive drugs, and many have been marketed. The drugs may work by reducing the power of the heartbeat, by dilating the blood vessels or by increasing the excretion of salts and water in the urine (diuresis). Antihypertensive treatment has greatly improved the prognosis of patients with high blood pressure by cutting the frequency of heart and renal failure (see KIDNEYS, DISEASES OF), stroke, and coronary thrombosis (see HEART, DISEASES OF). Drugs used for treatment can be classi?ed as follows: diuretics; vasodilator antihypertensives; centrally acting antihypertensives; adrenergic neurone-blocking drugs; alpha-adrenoreceptorblocking drugs; drugs affecting the renin-angiotensin system; ganglion-blocking drugs; and tyrosine hydroxylase inhibitors. The drugs prescribed depend on many factors, including the type of hypertension being treated. Treatment can be di?cult because of the need to balance the e?ectiveness of a drug in reducing blood pressure against its side-effects.... antihypertensive drugs

One third of those taking tranquillisers become addicted. One of the problems of psychological dependence is the discomfort of withdrawal symptoms.
Symptoms. Tremors, restlessness, nausea and sleep disturbance. The greater potency of the drug, the higher the rebound anxiety. Many drugs create stress, weaken resistance to disease, tax the heart and raise blood sugar levels.
Drugs like Cortisone cause bone loss by imperfect absorption of calcium. Taken in the form of milk and dairy products, calcium is not always absorbed. Herbs to make good calcium loss are: Horsetail, Chickweed, Slippery Elm, Spinach, Alfalfa.
Agents to calm nerves and promote withdrawal may augment a doctor’s prescription for reduction of drug dosage, until the latter may be discontinued. Skullcap and Valerian offer a good base for a prescription adjusted to meet individual requirements.
Alternatives. Teas: German Chamomile, Gotu Kola, Hops, Lime flowers, Hyssop, Alfalfa, Passion flower, Valerian, Mistletoe, Oats, Lavender, Vervain, Motherwort. 1 heaped teaspoon to each cup boiling water; infuse 5-15 minutes; half-1 cup thrice daily.
Decoctions: Valerian, Devil’s Claw, Siberian Ginseng, Lady’s Slipper. Jamaica Dogwood, Black Cohosh.
Tablets/capsules. Motherwort, Dogwood, Valerian, Skullcap, Passion flower, Mistletoe, Liquorice. Powders. Formulae. Alternatives. (1) Combine equal parts Valerian, Skullcap, Mistletoe. Or, (2) Combine Valerian 1; Skullcap 2; Asafoetida quarter. Dose: 500mg (two 00 capsules or one-third teaspoon) thrice daily. Formula No 2 is very effective but offensive to taste and smell.
Practitioner. Tincture Nucis vom. once or twice daily, as advised.
Aloe Vera gel (or juice). Russians tested this plant on rabbits given heavy drug doses and expected to die. Their survival revealed the protective property of this plant: dose, 1 tablespoon morning and evening. Aromatherapy. Sniff Ylang Ylang oil. Lavender oil massage for its relaxing and stress-reducing properties.
Diet. Avoid high blood sugar levels by rejecting alcohol, white flour products, chocolate, sugar, sweets and high cholesterol foods.
Supplements. Daily. Multivitamins, Vitamin B-complex, B6, Vitamin C 2g, Minerals: Magnesium, Manganese, Iron, Zinc. Change of lifestyle. Stop smoking. Yoga.
Notes. “Do not withdraw: insulin, anticoagulants, epileptic drugs, steroids, thyroxin and hormone replacement therapy (the endocrine glands may no longer be active). Long-term tranquillisers e.g., Largactil or any medicament which has been used for a long period. Patients on these drugs are on a finely-tuned medication the balance of which may be easily disturbed.” (Simon Mills, FNIMH)

The Committee on Safety of Medicines specifically warns against the abrupt cessation of the Benzodiazepines and similar tranquillisers because of the considerable risk of convulsions. ... drug dependence
ARRHYTHMIA is a variation in the normal rhythm of the heartbeat. Management of the condition requires accurate diagnosis of the type, and ELECTROCARDIOGRAPHY is vital in this process (see HEART, DISEASES OF). Drug treatment is usually part of the management, and antiarrhythmic drugs can be divided clinically into those that act on supraventricular arrhythmias, those that act on both supraventricular and ventricular arrythmias, and those that act on ventricular arrythmias. Respective examples are VERAPAMIL, DISOPYRAMIDE and LIDOCAINE. This large group of drugs can also be classi?ed according to their effects on the electrical reactions of active myocardial cells. The many drugs available are described in the British National Formulary.... antiarrhythmic drugs

These widely used drugs include a range of different preparations which relieve DEPRESSION. All the antidepressants available at the time of writing are more or less equally e?ective. In studies where patients agree to take either antidepressants or identical dummy PLACEBO pills (without knowing which), at least two-thirds of those who receive antidepressants feel much better within three months, while fewer than one-third of those on placebos recover naturally in the same period. In general these drugs are useful for severe and moderate depression including postnatal illness; they are not e?ective in milder forms of depression although they may be tried for a short time if other therapies have failed.
The most widely prescribed type of antidepressants are the tricyclics, so-called because their molecular structure includes three rings. The other commonly used types are named after the actions they have on chemicals in the brain: the SELECTIVE SEROTONIN-REUPTAKE INHIBITORS (SSRIS) and the MONOAMINE OXIDASE INHIBITORS (MAOIS) – see also below. All types of antidepressant work in similar ways. Tricyclic antidepressants have cured depression in millions of people, but they can cause unpleasant side-effects, particularly in the ?rst couple of weeks. These include SEDATION, dry mouth, excessive sweating, CONSTIPATION, urinary problems, and impotence (inability to get an erection). Up to half of all people prescribed tricyclic drugs cannot tolerate the side-effects and stop treatment before their depression is properly treated. More seriously, tricyclics can upset the rhythm of the heart in susceptible people and should never be given in the presence of heart disease.
The SSRIs are newer, coming into wide use in the late 1980s. They increase the levels in the brain of the chemical messenger SEROTONIN, which is thought to be depleted in depression. Indeed, the SSRIs are as e?ective as tricyclics and, although they can cause nausea and excessive sweating at ?rst, they generally have fewer side-effects. Their main disadvantage, however, is that they cost much more than the most commonly used tricyclic, amitriptyline. On the other hand, they are more acceptable to many patients and they cause fewer drop-outs from treatment – up to a quarter rather than a half. The money saved by completed, successful treatment may outweigh the prescribing costs. SSRIs have been reported as associated with an increased risk of suicide.
Another group of antidepressants, the MAOIs, have been in use since the late 1950s.
They are stimulants, rather than sedatives, and are particularly helpful for people who are physically and mentally slowed by depression. They work well but have one big disadvantage – a dangerous interaction with certain foods and other drugs, causing a sudden and very dangerous increase in blood pressure. People taking them must carry an information card explaining the risk and listing the things that they should avoid. Because of this risk, MAOIs are not used much now, except when other treatments have failed. A new MAOI, moclobemide, which is less likely to interact and so cause high blood pressure, is now available.
LITHIUM CARBONATE is a powerful antidepressant used for intractable depression. It should be used under specialist supervision as the gap between an e?ective dose and a toxic one is narrow.
St John’s Wort is a popular herbal remedy which may be e?ective, but which is handicapped by di?erences of strength between di?erent preparations or batches. It can interact with a number of conventional drugs and so needs to be used cautiously and with advice.
In general, antidepressants work by restoring the balance of chemicals in the brain. Improved sleep and reduced anxiety are usually the ?rst signs of improvement, particularly among people taking the more sedative tricyclic drugs. Improvement in other symptoms follow, with the mood starting to lift after about two weeks of treatment. Most people feel well by three months, although a few residual symptoms, such as slowness in the mornings, may take longer to clear up. People taking antidepressants usually want to stop them as soon as they feel better; however, the risk of relapse is high for up to a year and most doctors recommend continuing the drugs for around 4–6 months after recovery, with gradual reduction of the dose after that.
Withdrawal reactions may occur including nausea, vomiting, headache, giddiness, panic or anxiety and restlessness. The drugs should be withdrawn gradually over about a month or longer (up to six months in those who have been on maintenance treatment).
A wide range of antidepressant drugs is described in the British National Formulary. Examples include:
Tricyclics: amitryptyline, imipramine, doxepin.
MAOIs: phenelzine, isocarboxazid.
SSRIs: citalopram, ?uoxetine, paraxtene. (Antidepressant drugs not in these three
groups include ?upenthixol, mertazapine and venlafaxine.)... antidepressant drugs

A group of drugs, also known as thrombolytics, with the ability to break down the protein FIBRIN, the prime constituent of blood clots (see THROMBUS; THROMBOSIS). They are used to disperse blood clots that have formed in the vessels of the circulatory system. The group includes STREPTOKINASE, alteplase and reteplase. The drugs work by activating PLASMINOGEN to form PLASMIN which degrades ?brin and breaks up the blood clot (see COAGULATION).... fibrinolytic drugs

Green Tea comes with such a host of health benefits, that it’s called the ‘wonder herb’ by tea drinkers and medical practitioners alike.
Drinking green tea lowers cancer risk and also inhibits carcinogenic in cigarettes and other compounds when imbibed. Green Tea contains potent antioxidants called polyphenols, which help suppress free radicals. Green tea also stops certain tumors from forming. Green tea lowers cholesterol and triglyceride levels and thereby promotes heart health. Green tea also lowers blood pressure, prevents and fights tooth decay and dental issues, and inhibits different viruses from causing illnesses.... green tea
Andrographis paniculataAcanthaceaeSan: Bhunimbah, KiratatiktahHin: Kakamegh, Kalpanath
Ben: Kalmegh
Mal: Nilaveppu, Kiriyattu Tam: Nilavempu Kan: KreataImportance: Kalmegh, the Great or Green Chiretta is a branched annual herb. It is useful in hyperdipsia, burning sensation, wounds, ulcers, chronic fever, malarial and intermittent fevers, inflammations, cough, bronchitis, skin diseases, leprosy, pruritis, intestinal worms, dyspepsia, flatulence, colic, diarrhoea, dysentery, haemorrhoids and vitiated conditions of pitta (Warrier et al, 1993). It is used to overcome sannipata type of fever, difficulty in breathing, hemopathy due to the morbidity of kapha and pitta, burning sensation, cough, oedema, thirst, skin diseases, fever, ulcer and worms. It is also useful in acidity and liver complaints (Aiyer and Kolammal, 1962). The important preparations using the drug are Tiktakagheta, Gorocandi gulika, Candanasava, Panchatiktam kasaya, etc. (Sivarajan et al, 1994). A preparation called “Alui” is prepared by mixing powdered cumin (Cuminium cyminum) and large cardamom (Amomum subulatum) in the juice of this plant and administered for the treatment of malaria (Thakur et al, 1989). It is also a rich source of minerals.Distribution: The plant is distributed throughout the tropics. It is found in the plains of India from U.P to Assam, M.P., A.P, Tamil Nadu and Kerala, also cultivated in gardens.Botany: Andrographis paniculata (Burm.f.) Wall ex.Nees belongs to the family Acanthaceae. It is an erect branched annual herb, 0.3-0.9m in height with quadrangular branches. Leaves are simple, lanceolate, acute at both ends, glabrous, with 4-6 pairs of main nerves. Flowers are small, pale but blotched and spotted with brown and purple distant in lax spreading axillary and terminal racemes or panicles. Calyx-lobes are glandular pubescent with anthers bearded at the base. Fruits are linear capsules and acute at both ends. Seeds are numerous, yellowish brown and sub-quadrate (Warrier et al,1993).Another species of Andrographis is A. echioides (Linn.) Nees. It is found in the warmer parts of India. The plant is a febrifuge and diuretic. It contains flavone-echiodinin and its glucoside-echioidin (Husain et al, 1992).Agrotechnology: The best season of planting Andrographis is May-June. The field is to be ploughed well, mixed with compost or dried cowdung and seedbeds of length 3m, breadth 1/2m and 15cm height are to be taken at a distance of 3m. The plant is seed propagated. Seeds are to be soaked in water for 6 hours before sowing. Sowing is to be done at a spacing of 20cm. Seeds may germinate within 15-20 days. Two weedings, first at one month after planting and the second at 2 month after planting are to be carried out. Irrigation during summer months is beneficial. The plant is not attacked by any serious pests or diseases. Flowering commences from third month onwards. At this stage, plant are to be collected, tied into small bundles and sun-dried for 4-5 days. Whole plant is the economic part and the yield is about 1.25t dried plants/ha (Prasad et al, 1997).Properties and activity: Leaves contain two bitter substances lactone “andrographolid” and “kalmeghin”. The ash contains sodium chloride and potassium salts. Plant is very rich in chlorophyte. Kalmeghin is the active principle that contains 0.6% alkaloid of the crude plant. The plant contains diterpenoids, andrographolide, 14-deoxy-11-oxo-andrographolide, 14-deoxy-11,12-dihydroandrographolide, 14-deoxy andrographolide and neoandrographolide (Allison et al, 1968). The roots give flavones-apigenin-7,4-dio-O-methyl ether, 5-hydroxy-7,8,2’,3’- tetramethoxyflavone, andrographin and panicolin and -sitosterol (Ali et al, 1972; Govindachari et al, 1969). Leaves contain homoandrographolide, andrographosterol and andrographone.The plant is vulnerary, antipyretic, antiperiodic, anti-inflammatory, expectorant, depurative, sudorific, anthelmintic, digestive, stomachic, tonic, febrifuge and cholagogue. The plant is antifungal, antityphoid, hepatoprotective, antidiabetic and cholinergic. Shoot is antibacterial and leaf is hypotensive(Garcia et al, 1980). This is used for the inflammation of the respiratory tract. In China, researchers have isolated the andrographolide from which soluble derivative such as 14-deoxy-11, 12-dehydro-andrographolide which forms the subject of current pharmacological and clinical studies. Apigenin 7,4’-O-dimethyl ether isolated from A. paniculata exhibits dose dependent, antiulcer activity in shay rat, histamine induced ulcer in guinea pigs and aspirin induced ulcers in rats. A crude substance isolated from methanolic extract of leaves has shown hypotensive activity. Pre-treatment of rats with leaf (500mg/kg) or andrographolide (5mg/kg) orally prevented the carbon tetrachloride induced increase of blood serum levels of glutamate-oxaloacetate transaminase in liver and prevented hepatocellular membrane.... green chiretta

Drugs are usually administered distant to their site of action in the body; they must then pass across cell membranes to reach their site of action. For example, drugs given by mouth must pass across the gut membrane to enter the bloodstream and then pass through the endothelium of vessel walls to reach the site of action in the tissues. This process is called absorption and may depend on lipid di?usion, aqueous di?usion, active transport, or pinocytosis – a process in which a cell takes in small droplets of ?uid by cytoplasmic engulfment.... drug absorption
Also known as ‘date rape’, this is an unwelcome phenomenon in which an intending rapist undermines a potential victim’s resistance by giving her a hypnotic drug such as benzodiazepine.

In the United Kingdom, controlled drugs are those preparations referred to under the Misuse of Drugs Act 1971. The Act prohibits activities related to the manufacture, supply and possession of these drugs, and they are classi?ed into three groups which determine the penalties for o?ences involving their misuse. For example, class A includes COCAINE, DIAMORPHINE, MORPHINE, LSD (see LYSERGIC ACID DIETHYLAMIDE and PETHIDINE HYDROCHLORIDE. Class B includes AMPHETAMINES, BARBITURATES and CODEINE. Class C includes drugs related to amphetamines such as diethylpropion and chlorphentermine, meprobamate and most BENZODIAZEPINES and CANNABIS.
The Misuse of Drugs Regulations 1985 de?ne the classes of person authorised to supply and possess controlled drugs, and lay down the conditions under which these activities may be carried out. In the Regulations, drugs are divided into ?ve schedules specifying the requirements for supply, possession, prescribing and record-keeping. Schedule I contains drugs which are not used as medicines. Schedules II and III contain drugs which are subject to the prescription requirements of the Act (see below). They are distinguished in the British National Formulary (BNF) by the symbol CD and they include morphine, diamorphine (heroin), other opioid analgesics, barbiturates, amphetamines, cocaine and diethylpropion. Schedules IV and V contain drugs such as the benzodiazepines which are subject to minimal control. A full list of the drugs in each schedule can be found in the BNF.
Prescriptions for drugs in schedules II and III must be signed and dated by the prescriber, who must give his or her address. The prescription must be in the prescriber’s own handwriting and provide the name and address of the patient and the total quantity of the preparation in both words and ?gures. The pharmacist is not allowed to dispense a controlled drug unless all the information required by law is given on the prescription.
Until 1997 the Misuse of Drugs (Noti?cation and Supply of Addicts) Regulations 1973 governed the noti?cation of addicts. This was required in respect of the following commonly used drugs: cocaine, dextromoramide, diamorphine, dipipanone, hydrocodeine, hydromorphone, levorphanol, methadone, morphine, opium, oxycodone, pethidine, phenazocine and piritranide.
In 1997 the Misuse of Drugs (Supply to Addicts) Regulations 1997 revoked the 1973 requirement for noti?cation. Doctors are now expected to report (on a standard form) cases of drug misuse to their local Drug Misuse Database (DMD). Noti?cation by the doctor should be made when a patient ?rst presents with a drug problem or when he or she visits again after a gap of six months or more. All types of misuse should be reported: this includes opioids, benzodiazepines and central nervous system stimulants. The data in the DMD are anonymised, which means that doctors cannot check on possible multiple prescribing for drug addicts.
The 1997 Regulations restrict the prescribing of diamorphine (heroin), Diconal® (a morphine-based drug) or cocaine to medical practitioners holding a special licence issued by the Home Secretary.

One of the most popular drinks in China, Dragon Well tea is part of the green teas family, having an inviting and a toasty flavor. A truly enjoyable and spectacular cup of tea.
Description of Dragon Well tea
Dragon Well tea is a type of pan-fried green tea, most commonly named Longjing tea from Hangzhou, Zheijang province in China, where is produced mainly by hand. During the production process, the Dragon Well is dried under a wood-fired Chinese pan called “wok”. This process removes the green, grassy taste and also inhibits enzyme activity. Due to the widespread opinion in China that the Dragon Well tea has a cooling effect, its popularity significantly increases especially during the spring and summer seasons.
Often called the national tea of China, Dragon Well tea is often served to head of states and foreign delegations during their visits in China. Presented as a tribute to many generations, it was given even to Richard Nixon during his memorable encounter with Mao Zedong.
This tea is very popular because of its unique properties: jade color, vegetative aroma, mellow chestnut flavor and singular shape. It has a buttery, nutty, rich texture and an enjoyable dry finish.
Commonly, Dragon Well tea is graded using a scale of six levels from superior quality to low quality so it is advisable to chose wisely when you decide to buy it. When the flavor can barely be sensed, it is clear that you deal with a poor quality.
How to store the Dragon Well tea
If the tea is sealed, keep it in a freezer. Cover with a box to insulate from temperature change. In order to get warm, leave it to room temperature before opening. This prevents condensation.
After opening the package of Dragon Well tea, it is best to keep it away from light, moisture, smell and heat in an airtight container.
Ingredients of Dragon Well tea
Like most green teas, the Dragon Well tea contains amino acids, vitamins, flavonoids, proteins, calcium, iron, fluorine, theine and has one of the highest concentrations of catechins among teas, second only to white teas.
How to brew Dragon Well tea
When it comes to brewing Dragon Well tea, the best choice is a clear glass teacup, so that you can see the beauty of the leaves as they dance and unfurl in the water. It is really spectacular. Quality of tea is related directly to the beauty of the buds. Glass is most suitable also because it disperses heat quickly and prevents over-steeping. If you see that the buds have reached the bottom, this means that the tea is ready to drink.
You should infuse a small amount of leaves in high temperature water for as long as it takes.
Pour hot water at approximately 80 - 90 degrees Celsius. Immerse until most of the tea buds has sink to the bottom of the glass and the tea liquor turns yellow. This will take 5 to 10 minutes for the first infusion. During soaking, the tea brings out a soft, pure aroma, a yellow-green color and a rich flavor.
Decant and leave a small quantity as you may use it as the seed for the next infusion.
Infuse for another 2 to 4 times with progressively shorter steeping time.
Health Benefits of Dragon Well tea
All tea comes from the same plant named Camellia sinensis. The method of production creates the different types of tea. Dragon Well tea contains the highest content of antioxidant compounds. Antioxidants are proven to fight against certain cancers, lower cholesterol levels and blood pressure, reduce the likely-hood of getting the flu and other infections, boosting the immune function of our body and help reduce the signs of aging. It is also a fat burning accelerator so let’s not forget its important benefits for diets. There’s also enough fluoride found in green tea to aid against plaque and other oral bacteria.
Side effects of Dragon Well tea
Like any other green tea, Dragon Well tea may have few side effects like restlessness, palpitations, insomnia, anxiety, irritability, increased heart rate, and elevated blood pressure due to the caffeine content. It may also cause pain in the stomach area or reduce the body’s absorption of iron by 25% so it is contraindicated to people with anemia, faintness, gastritis with hyperacidity, stomach and duodenal ulcer.
In spite of few side effects, it is worth trying it and get to know its flavor. The spectacle of drinking this type of tea is truly unique and the flavor really satisfying.... discover the spectacle of dragon well green tea
These drugs reduce the amount of low-density LIPOPROTEINS, which transport CHOLESTEROL and triglycerides (see TRIGLYCERIDE) in the blood, or raise the concentration of high-density lipoproteins. The aim is to reduce the progression of ATHEROSCLEROSIS and therefore help prevent coronary heart disease (see HEART, DISEASES OF). These drugs should be combined with reducing other risk factors for raised lipid concentrations, such as a high-fat diet, smoking and obesity. Lipid-regulating drugs include STATINS, ?brates, anion-exchange resins, and NICOTINIC ACID, which may be used singly or in combination under careful medical supervision (see HYPERLIPIDAEMIA).... lipid-regulating drugs

Gunpowder tea is a Chinese tea made in Zhejiang Provence, China. It’s a form of green tea made out of withered, steamed, rolled and dried leaves. The name of gunpowder tea was given due to the fact that the small leaves which are tightly rolled into small round pellets, look like gunpowder.
Gunpowder tea, like most green teas, comes from the Camellia Sinensis plant, which is a small leaved bush with many stems that can reach to almost 3 meters.
There are many types of
gunpowder tea, judging by the type of the leaves:
- Pingshui gunpowder which is the most common type, has larger pellets and a more powerful flavor. It is sold as Temple of Heaven Gunpowder.
- Formosa Gunpowder which is grown in Taiwan. Its fragrance is very close to the Taiwanese oolong tea.
- Ceylon Gunpowder is produced at high altitudes in Sri Lanka.
Brewing Gunpowder Tea
There are many ways to brew
gunpowder tea, but the most handy and common preparation is by putting 1 tablespoon of gunpowder leaves for every 5 ounces of water. The gunpowder must be steeped up to 1-2 minutes into water, boiled at 160 degrees. After that, it can be streamed and served.
It is not recommended to put milk or sweeteners in it such as honey or sugar, since the tea already has a soft honey flavor.
What does Gunpowder Tea contain?
Gunpowder tea, since it is classified as a green tea, it shares all of the components of classic green tea, mainly antioxidant ingredients such as green tea catechins (GTC).
The importance of antioxidants is very high since they find and eliminate disease-causing free radicals that can develop cancer or even damage the DNA structure.

Because antioxidants fight free-radicals, the
gunpowder tea helps maintaining your general health.
- It helps fight cancer due to the fact that antioxidants neutralize and reduce the damage that free radicals can cause to cells.
- Prevents type II diabetes due to the fact that green tea may improve insulin sensibility and glucose tolerance.
- It can also be used for treating loose digestion or indigestion. The antioxidants help reduce inflammations that are associated with ulcerative colitis and Chron’s disease.
- Heals wounds and controls bleeding because of the strong fluoride content.
- Slows aging process.
Gunpowder Tea side effects
The general side effects that
gunpowder tea can have are the same as the ones normal green tea present, such as nausea or stomach ache. Since it has caffeine,gunpowder tea can cause insomnia, nervousness or irritability, so avoid drinking it in the evening or before bed.
Also it can cause iron deficiency, which is why people who take iron supplements are strongly advised not to drink any type of green tea, or to drink it at least 2 hours before taking the supplements or 4 hours after taking them.
All in all,
gunpowder tea has more benefits for your health than side effects. It is good to drinkgunpowder tea, because it helps your immune system and provides you with all the vitamins you need in order to stay healthy.... gunpowder tea - a popular chinese green tea
See also MEDICINES. Government legislation covers the manufacture, sale and prescription of drugs in the UK. As well as stating which drugs may be sold over the counter (OTC) without a doctor’s or dentist’s prescription, and those which can be obtained only with such a prescription, government regulations determine the extent of availability of many substances which are liable to be abused – see Misuse of Drugs Act 1971 (below). The Misuse of Drugs Regulations 1985 de?ne those individuals who in their professional capacity are authorised to supply and possess controlled drugs: see the schedules of drugs listed below under the 1985 regulations.
Misuse of Drugs Act 1971 This legislation forbids activities relating to the manufacture, sale and possession of particular (controlled) drugs. These are classi?ed into three grades according to their dangers if misused. Any o?ences concerning class A drugs, potentially the most damaging when abused, carry the toughest penalties, while classes B and C attract lesser penalties if abused.
Class A includes: cocaine, dextromoramide, diamorphine (heroin), lysergic acid (LSD), methadone, morphine, opium, pethidine, phencyclidine acid and injectable preparations of class B drugs.
Class B includes: oral amphetamines, barbiturates, codeine, glutethimide, marijuana (cannabis), pentazocine and pholcodine.
Class C includes: drugs related to the amphetamines, anabolic and androgenic steroids, many benzodiazepines, buprenorphine, diethyl propion, human chorionic gonadotrophin (HCG), mazindol, meprobamate, pemoline, phenbuterol, and somatropin.
Misuse of Drugs Regulations 1985 These regulations de?ne those people who are authorised in their professional capacity to supply and possess controlled drugs. They also describe the requirements for legally undertaking these activities, such as storage of the drugs and limits on their prescription.
Drugs are divided into ?ve schedules and some examples follow.
I: Almost all are prohibited except in accordance with Home O?ce authority: marijuana (cannabis), LSD.
II: High potential for abuse but have
accepted medical uses: amphetamines, cocaine.
III: Lower potential for abuse: barbiturates, meprobamate, temazepam.
IV: Lower potential for abuse than I to III. Minimal control: benzodiazepines.
V: Low potential for abuse: generally compound preparations containing small amounts of opioids: kaolin and morphine (antidiarrhoeal medicine), codeine linctus (cough suppressant).

Hojicha tea is a type of Japanese green tea which is made from the sun-grown Japanese green tea known as
bancha, harvested from the tea plant later in the season.Hojicha tea is roasted in a porcelain pot over charcoal at a high temperature, fact that alters the leaf color from green to reddish-brown.
Hojicha tea has been certified as organic by the government of Japan.
Brewing Hojicha tea
There are many ways of preparing Hojicha tea, depending on each and other person’s taste. For example, shorter infusions of
Hojicha tea may produce a fresh flavor, while longer infusions are more developed and have a “nuttier” taste.
For starters, heat the the teapot with boiling water. The heat of the water is the one that brings out the aroma of
Hojicha tea, so it shouldn’t be boiled at more than 180°F (80 degrees Celsius). The next step is adding the tea inside the teapot, one tablespoon of tea for each serving, when the water has just boiled. Then, depending on the flavor that you want, let it steep between 30 - 90 seconds. In the end, pour the tea into a cup, making sure to use all the water in the teapot.
Hojicha tea is usually served after the evening meal or before bed since it has lower caffeine content than other green teas.
Components of Hojicha tea
The main components of
Hojicha tea are, like most green teas, tannin, caffeine, theanine (which is an amino acid) and Vitamin C. Hojicha tea is known for the low amounts of caffeine and tannin (less astringency), fact that makes the tea easier to drink in the evening and it is also more suitable for children and elders. Since it lacks in caffeine, some people even drinkHojicha tea to replace coffee, or before bed for a deep and calm sleep.
Hojicha tea benefits
Hojicha tea has a lot of health benefits, even though the same process that removes the caffeine also reduces the antioxidants. Due to the fact that Hojicha tea is actually a green tea, it basically presents the same benefits as any other green tea:
- Hojicha tea helps fighting against diseases caused by viruses or bacteria and strengthens the immune system.
- Hojicha tea helps protect against cardiovascular diseases, tumors and it’s also an important element when it comes to cancer prevention.
- Hojicha tea is a strong allied in the process of weight loss.
- Hojicha tea gives an overall well-being and helps you relax.
Hojicha tea side effects
Hojicha tea, because of the low caffeine, tannin and theanine content doesn’t actually present any particular side effects. However, being a green tea you should be aware of the following side effects that may appear if it is not consumed properly:
- You should not drinkHojicha tea when you are pregnant or breastfeeding.
- If you suffer from anemia or iron deficiency. According to some studies, green tea extract reduces the absorption of iron by 25%.
- It is advised not to drink green tea on an empty stomach since it could cause liver damage.
- Avoid green tea if you have kidney disorders or stomach ulcers.
All in all, try not to drink more than 6 cups a day of Hojicha green tea.
If you are a green tea drinker or if you just want to try a different tea taste, besides the herbal flavor that most green teas have, you should not miss
Hojicha tea. The components of Hojicha tea helps improve your immune system and, generally, keeps you healthy. It’s perfect for cold winter days!

These act by inhibiting the formation of PROSTAGLANDINS which are mediators of INFLAMMATION. They act both as ANALGESICS to relieve pain, and as inhibitors of in?ammation. Aspirin is a classic example of such a compound. Newer compounds have been synthesised with the aim of producing fewer and less severe side-effects. They are sometimes preferred to aspirin for the treatment of conditions such as RHEUMATOID ARTHRITIS, OSTEOARTHRITIS, sprains, strains and sports injuries. Their main side-effects are gastrointestinal: gastric ulcers and gastric haemorrhage may result (see STOMACH, DISEASES OF). This is because prostaglandins are necessary for the production of the mucous protective coat in the stomach and, when the production of prostaglandin is inhibited, the protection of the stomach is compromised. NSAIDs should therefore be used with caution in patients with DYSPEPSIA and gastric ulceration. The various nonsteroidal anti-in?ammatory drugs di?er little from each other in e?cacy, although there is considerable variation in patient response. Ibuprofen is one of the ?rst choices in this group of drugs as it combines good e?cacy with a low incidence of side-effects and administration is only required twice daily. Other drugs in this series include diclofenac, fenbufen, fenclofenac, fenoprofen, feprazone, ?urbiprofen, indomethacin, indoprofen, ketoprofen, ketorolac, naproxen, piroxicam, sulindac, tiaprofenic acid and tolmetin.... non-steroidal anti-inflammatory drugs (nsaids)

This group of drugs is one of three main types of drugs used to treat DEPRESSION, and was the ?rst to be introduced (in the 1950s). Tricyclic drugs work by blocking the re-uptake of the neurotransmitters SEROTONIN and NORADRENALINE (see NEUROTRANSMITTER), thus increasing the amount of the neurotransmitters at the nerve cell’s receptors. In people with depression, fewer neurotransmitters than normal are released, resulting in a slowing of neural activities. The drugs have a sedative e?ect, which can be useful for depressives with sleep problems, and an antimuscarinic action which can cause dry mouth and constipation (see ANTIMUSCARINE). Overdosage can produce COMA, ?ts (see SEIZURE) and irregular heart rhythm (ARRHYTHMIA). They are sometimes used for treating bed-wetting.

Yerba Mate Tea remained unknown to the general public until a while ago, when the South American tea gained an impressive popularity among world-wide practitioners. Yerba Mate is a small tree that grows mainly in hot climate regions such as Brazil, Argentina and Paraguay.
Yerba Mate Tea can be made from this tree’s leaves and stems. Ancient civilizations believed that this tea was the drink of gods thanks to its curative properties and its ability to purify houses and temples. The custom is to drink Yerba Mate tea from a special container called bombilla and using a straw.
Yerba Mate Tea Properties
Yerba Mate Tea has a bitter-sweet taste and is very similar to the camellia sinensis tea. Scientists found that Yerba Mate tea contains 196 active ingredients, making this South American tea one of the richest decoctions on Earth.
The main substances of this tea are: tannins, antioxidants, polyphenols, amino acids, saponins, vitamins and flavonoids. Herbalists discovered that Yerba Mate Tea contains all the ingredients capable to sustain life. Many recent studies refer to this tea as “the new green tea”.
Yerba Mate Tea Benefits
Aside from its cultural background, Yerba Mate Tea is one of the best teas on Earth, thanks not only to its numerous chemical ingredients, but also to a large amount of diseases that can treat. Although in the Latin Americas this tea is as popular (if not more popular) than the tea, it remains still unknown to European public. However, Yerba Mate Tea may come in hand in case you’re suffering from one of the following problems:
- Low energy level and fatigue, by giving your health system a boost.
- Central nervous system problems, such as headaches and severe migraines, by helping your body produce and release more endorphins.
- Gastrointestinal disorders, such as stomach pains and intestinal infections, flushing out of your system all microbes and unwanted parasites.
How to make Yerba Mate Tea Infusion
Preparing Yerba Mate Tea couldn’t be any easier. Just take the dried lives (if you live in South America, try to use the freshly-picked ones. They have a stronger flavor), put them in a teapot and add boiling water. Use a teaspoon of every cup of tea you want to make and wait 15 minutes for the wonderful benefits of this tea to be released. Drink it hot or cold, from a glass or a bombilla.
Yerba Mate Tea Side Effects
There are no reported cases of Yerba Mate Tea side effects. However, in order to avoid any kind of complications, it’s best not to drink more than 4 cups of tea per day. If you’re still having doubts about taking a treatment based on Yerba Mate Tea, talk to a specialist and gather more information.
Yerba Mate Tea Contraindications
When taken in high dosages, Yerba Mate Tea may lead to a number of negative reactions from your body, such as lung cancer, esophageal cancer, laryngeal cancer and kidney cancer. Before starting any herbal treatment, talk to a specialist in order to be informed of the implied risks.
If you feel confident in your health, you already have your doctor’s ok on this matter andyou’re willing to follow a list of basic instructions, give Yerba Mate Tea a try and enjoy its great benefits!... yerba mate tea - the new green tea
Natural or synthetic androgen hormones used as drugs; one of the most important is testosterone. These drugs are used in the treatment of male hypogonadism (underactivity of the testes) to stimulate the development of sexual characteristics.
Androgen drugs are occasionally used to treat certain types of breast cancer. They have been widely used by sportsmen wishing to increase muscle bulk and strength, a practice that is dangerous to health (see steroids, anabolic).
Adverse effects include fluid retention, weight gain, increased blood cholesterol, and, rarely, liver damage. When taken by women, the drugs can cause male characteristics, such as facial hair, to develop.
androgen hormones A group of hormones that stimulate the development of male sexual characteristics.
Androgens are produced by specialized cells in the testes in males and in the adrenal glands in both sexes. The ovaries secrete very small quantities of androgens until the menopause. The most active androgen is testosterone, which is produced in the testes. The production of androgens by the testes is controlled by certain pituitary hormones, called gonadotrophins. Adrenal androgens are controlled by ACTH, another pituitary hormone.
Androgens stimulate male secondary sexual characteristics at puberty, such as the growth of facial hair and deepening of the voice. They have an anabolic effect (they raise the rate of protein synthesis and lower the rate at which it is broken down). This increases muscle bulk and accelerates growth. At the end of puberty, androgens cause the long bones to stop growing. They stimulate sebum secretion, which, if excessive, causes acne. In early adult life, androgens promote male-pattern baldness.
Androgen deficiency may occur if the testes are diseased or if the pituitary gland fails to secrete gonadotrophins. Typical effects include decreased body and facial hair, a high-pitched voice, underdevelopment of the genitalia, and poor muscle development.
Overproduction of androgens may be the result of adrenal disorders (see adrenal tumours; adrenal hyperplasia, congenital), of testicular tumours (see testis, cancer of), or, rarely, of androgensecreting ovarian tumours (see ovary, cancer of).
In men, excess androgens accentuate male characteristics; in boys, they cause premature sexual development.
In women, excess androgens cause virilization, the development of masculine features such as an increase in body hair, deepening of the voice, clitoral enlargement, and amenorrhoea.... androgen drugs

A group of drugs used to relieve the symptoms of anxiety. Benzodiazepine drugs and beta-blocker drugs are the 2 main types, although antidepressant drugs may occasionally be used. Benzodiazepine drugs promote mental and physical relaxation; they can also be used to treat insomnia, but their use for this purpose is avoided because they are addictive. Beta-blockers reduce only the physical symptoms of anxiety, such as shaking and palpitations, and are not addictive.... antianxiety drugs

A group of sedative drugs that work by depressing activity within the brain. They include thiopental and phenobarbital. In the past, barbiturates were widely used as antianxiety drugs and sleeping drugs but have been largely replaced by benzodiazepine drugs and other nonbarbiturates. Barbiturates are now strictly controlled because they are habit-forming and widely abused. An overdose can be fatal, particularly in combination with alcohol, which dangerously increases the depressant effect on the brain (including suppression of the respiratory centre). However, phenobarbital is still commonly used as an anticonvulsant drug in the treatment of epilepsy.
