Drug Interactions: From 1 Different Sources
Many patients are on several prescribed drugs, and numerous medicines are available over the counter, so the potential for drug interaction is large. A drug may interact with another by inhibiting its action, potentiating its action, or by simple summation of effects.
The interaction may take place:
(1) Prior to absorption or administration – for example, antacids bind tetracycline in the gut and prevent absorption.
(2) By interfering with protein binding – one drug may displace another from binding sites on plasma proteins. The action of the displaced drug will be increased because more drug is now available; for example, anticoagulants are displaced by analgesics.
(3) During metabolism or excretion of the drug – some drugs increase or decrease the activity of liver enzymes which metabolise drugs, thus affecting their rate of destruction; for example, barbiturates, nicotine, and alcohol all activate hepatic enzymes. Altering the pH of urine will affect the excretion of drugs via the kidney.
(4) At the drug receptor – one drug may displace another at the receptor, affecting its e?cacy or duration of action.

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)

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

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.
