                                                                           Datura

                                                              Datura

A wild plant in the Indo-Gangetic Plain.

One of the 50 fundamental herbs used in Chinese herbology.


                                                              fruits of Datura

MEDICINAL USES:-
Datura metel is known as an anticholinergic, meaning it reduces spasms by blocking the transmission of nerve impulses. Additionally, datura metel is a well-known plant with deliriant properties, or capable of causing hallucinations or delirium. It has been the choice of many cultures over the years for astral or shamanistic journeys, or as a rite of passage.
Its ability to control spasms has led to datura metel being used frequently in Chinese herbology to treat the wheezing of asthma, and in Vietnam datura metel is added to asthmatic cigarettes. Great care must be taken when using this herb, as the toxic dose is very close to the medicinal dose. The wrong dosage can induce hallucinations, severe intoxication, and even death. Use of datura metel should be closely monitored by an experienced practitioner trained in herbology.
The alkanoids contained within the plant is what makes it effective as a anesthetic. Alkanoids are chemical compounds produced by a large number of organisms, and many have pharmaceutical effects. The alkanoids in datura are hycosamine, hycosine, and atropine.

Ginkgo biloba

                                                              Ginkgo biloba
                                               single bilobed leaf of G. biloba


Other Names: Ginkgo, Maidenhair Tree, Golden Fossil Tree


Medicinal use of G. biloba:-

 Extracts of the fruit and leaves of the Ginkgo tree have been used in China for over 5,000 years. Ginkgo Biloba has been historically used in alternative medicine for Heart disease, Kidney disorders, Alzheimer's, Asthma and as an energy builder. Recently western researchers have been studying ginkgo biloba as a treatment for senility, hardening of the arteries, and as a treatment for oxygen deprivation. In over 34 human studies on Ginkgo it increases the body's production of the universal energy molecule adenosine triphosphate, commonly called ATP. This activity has been shown to boost the brains energy metabolism of glucose and increase electrical activity. Scientists also discovered that ginkgo contains an abundance of useful compounds including the antioxidants Vitamin C and carotenoids, but it is the flavanoid compounds collectively known as "ginkgolides" that are the most remarkable. The ginkgo flavonoids act specifically to dilate the smallest segment of the circulatory system, the micro-capillaries, which has a widespread affect on the organs, especially the brain. Researchers have also reported that Ginkgo extracts effectively increase blood circulation and increase oxygen levels in brain tissues. Ginkgo is also a powerful antioxidant that prevents platelet aggregation inside arterial walls, keeping them flexible and decreasing the formation of arteriosclerositic plaque. It has also been shown to help restore circulation to areas of the brain damaged by stroke. Ginkgo has a positive effect in Dementia cases, fighting free radicals in the blood system, protecting against chromosomal damage (proven with Chernobyl workers). Ischemia-induced spinal cord injury protection, heart muscle ischemia and reper-fusion injury protection. Protection against retinal damage, helping with tinnitus, headaches, vertigo, hearing loss, depression, allergies, atherosclerosis, cardiac arrhythmia, diabetic peripheral disease, eczema, glaucoma, impotency, retinitis, to treat asthma, to aid digestion, and bring back sexual energy as well as treating early stages of Alzheimer's disease. The brain is one of the most metabolically active tissues in the human body. It uses a great deal of energy which requires a steady supply of oxygen and glucose. Unlike most other tissues, the brain has very little energy reserve which makes it extremely susceptible to the effects of poor blood supply. When circulation is inadequate, the brain cannot function at its full capacity. The big news for ginkgo came in October 1997 when the Journal of the American Medical Association published the results of a study that confirmed that ginkgo had a positive effect in cases of dementia. They used only patients whose main problem was mental impairment, whether someone had termed it Alzheimer’s or not. They used every control imaginable and rated progress on three different scales to make sure that their results were accurate. Researchers even went so far as to switch everyone from the placebo to the real medicine and vice versa in the middle of the study. There is no doubt about it. Ginkgo stopped the progress of the disease in most cases, and many cases reversed the damage. A Swedish study showed that ginkgo improved the distance-vision of people who already showed signs of degeneration in the retina. The disease macular degeneration, a leading cause of blindness, is strongly related to hemorrhages in the fine blood vessels in the eye, possibly due to oxidative stress. By strengthening the tiny blood vessels in the eye, and by acting as an antioxidant, ginkgo provides a double whammy against eye diseases. It eliminates waste material and inhibits the clumping of blood platelets and prevents circulating platelets from sticking together, which contributes to heart problems, strokes and artery conditions. Ginkgo is an adaptogen herb, which helps the body with stressful situations. It is also helpful in the treatment of allergies, Alzheimer's disease, anxiety attacks, arthritis, ADD, circulatory disorders, cancer, coughs, depression, dizziness, equilibrium problems, headaches, heart & lung problems, memory loss, mood swings, muscular degeneration, tinnitus, toxic shock syndrome, varicose veins, vascular impotence & vertigo. Studies have shown that the length of time a person uses this plant leaf is very important. With ginkgo, the effectiveness may not be felt for twelve weeks. While most people note some improvement in just two to three weeks, others take longer to respond. Ginkgo biloba extracts are relatively considered safe and free of side effects, though taking very large doses may lead to diarrhea, nausea and vomiting, which can be controlled by reducing the amount consumed. Those taking blood thinners should consult with their physician before taking ginkgo biloba in high doses, due to their blood thinning tendencies. It is also advisable to discontinue use prior to surgery.
