It you want to drink a special type of herbal tea, try the rose petal tea. It is aromatic, with a pleasant taste, and you’re bound to enjoy it. It also has important health benefits. Find out more about rose petal tea!
About Rose Petal Tea
Rose petal tea is made from the petals of a flower most adored by many women: the rose. This woody perennial plant has over 100 species which grow in Asia, Europe, North America, and northwest Africa.
Roses grow as a group of erect shrubs, acting like climbing plants. Its stems often have small, sharp thorns. The leaves are oval-shaped with sharply-toothed edges, and they’re about 10cm long. The fruit is called rosehip; it is ripe from late summer to autumn, and it is edible. The flowers usually have 5 petals with two distinct lobes; they are usually pink, white, red, or yellow.
You can make tea both from the rose petals and from the rose’s fruit, the rosehip.
How to prepare Rose Petal Tea
When making rose petal tea, first make sure that the petals you use are free of pesticides. Roses from gardens and flower shops are usually treated with pesticides, and shouldn’t be used to make rose petal tea.
To enjoy rose petal tea, add about two handfuls of properly washed and dry rose petals to a pot with water for three cups of tea. Leave the pot over medium heat for 5 minutes, or until the petals have lost their original color, becoming darker. Stream to remove the petals and sweeten, if necessary, with honey or fruit juice.
Rose Petal Tea Components
Rose petal tea gets many active components from the rose petals: cyclic monoterpene alcohols, geraniol, citronellol and nerol are just a few important ones. It also includes long-chain hydrocarbons (nonadecane, heneicosane).
These active components lead to the many health benefits rose petal tea has.
Rose Petal Tea Benefits
Rose petal tea helps strengthen your immunity, and can be part of the treatment for colds. It is useful if you’ve got a fever, a runny nose, a sore throat, or bronchial congestion. Also, it helps clean your body of toxins.
Drinking rose petal tea can help during menstrual periods, if you’ve got a heavy menstrual flow. It can also reduce menstrual cramps, and helps regulate your period.
Rose petal tea is often used to treat diarrhea and dysentery. It can also help you fight against depression, fatigue and insomnia.
Rose petal tea also acts as a digestive aid, as it protects the gastrointestinal tract. It is often used to treat constipation, gastroenteritis, diarrhea, and dysentery; the tea also nourishes the gastric mucosa. You can drink rose petal tea to treat urinary tract infections, as well.
Rose Petal Tea Side Effects
No important side effects of rose petal tea have been noted. Still, it is considered best not to drink more than 5 cups of tea a day. If you drink too much, you might get some of these symptoms: headaches, loss of appetite, vomiting, diarrhea, insomnia, dizziness, and irregular heartbeats.

A synthetic analgesic and antispasmodic drug, which is used in the treatment of painful and spasmodic conditions in place of morphine and atropine. A prompt but short-lasting analgesic, it has less of a constipating e?ect than morphine but is less potent. Useful for analgesia during childbirth because it produces less respiratory depression in the baby than other opioids. Pethidine is one of the CONTROLLED DRUGS.... pethidine hydrochloride

(Mill.) Airy-Shaw.
Synonym: Apium crispum Mill.
Family: Umbelliferae; Apiaceae.
Habitat: Native to Europe, now cultivated throughout India.
English: Parsley.
Unani: Fitraasaaliyum, Karafs-e- Kohi.
Action: Diuretic (used for bladder disorders, painful urination, retention of excess fluid in the tissues), antispasmodic, uterine tonic, emmenagogue, sedative (used for PMS and menopausal hot flushes, also in prostatitis), carminative, expectorant, aperient, antiseptic, anti-inflammatory.
Key application: For flushing out the efferent urinary tract in disorders of the same and in prevention and treatment of kidney gravel. (German Commission E.) Contraindicated in kidney inflammations.The British Herbal Compendium approves the internal use of the herb for flatulent dyspepsia, dysuria and rheumatic conditions.The leaves and roots contain furo- coumarins—psoralen, 5-and 8-meth- oxy psoralen, imperatorin, oxypeuce- danin, iso-pimpinelin. Myristicin has been isolated from the leaf oil. The plant gave flavonoids—apiin, luteolin, apigenin-7-glucoside, luteolin-7-glu- coside among others.Myristicin showed high activity as an inducer of the detoxifying enzyme system, Glutathione S-transferase (GST) in the liver and small intestines of female mice (may be considered as a cancer chemoprotective agent).The flavonoids, particularly api- genin, have been shown to be anti- inflammatory, to inhibit histamine release and to act as a free radical scavenger. Apiole, a constituent of the volatile oil, is reportedly antipyretic and phthalides of the root, seed and leaf are sedative in mice.Both apiole and myristicin exhibit aquaretic and uterine stimulant activity, while sodium retention has been observed. (Natural Medicines Comprehensive Database, 2007.)In homoeopathy, the herb is used for the treatment urinary disorders—sudden urge to urinate with severe pain, dribbling of urine after urination, gleet discharge and for amenorrhoea and neuralgic dysmenorrhoea.... petroselinum crispum

(OCT) a class of optical tomographic techniques that allows extremely high-quality micrometre-resolution three-dimensional images to be obtained from within optical scattering media (e.g. biological tissue). OCT is proving valuable in ophthalmology, for noninvasive imaging of the ocular structures, and in cardiology for visualizing the interior of coronary arteries using a specialized *catheter. See also spectral domain optical coherence tomography.... optical coherence tomography

(CT) a form of X-ray examination in which the X-ray source and detector (CT scanner) rotate around the object to be scanned and the information obtained can be used to produce cross-sectional images (see cross-sectional imaging) by computer (a CT scan). A higher radiation dose is received by the patient than with some conventional X-ray techniques, but the diagnostic information obtained is far greater and should outweigh the increased risk. CT scanning can be used for all parts of the body. The data obtained can be used to construct three-dimensional images of structures of interest. See also multidetector computerized tomography; spiral CT scanning.... computerized tomography
(MDCT) a development of *spiral CT scanning that uses more than one array of detectors opposite the X-ray tube, so that more tissue can be included, with thinner cuts, in a single rotation of the machine. This is particularly important for three-dimensional reconstruction of tissues. It also allows volumetric scanning or *isotropic imaging, which are best achieved when the thickness of the slice is similar to the size resolution of the detectors in the other two planes. Modern CT scanners are now usually equipped with between 16 and 640 detector arrays. The technique is particularly valuable for imaging fast-moving structures, such as the heart.... multidetector computerized tomography
