Ephedra affects autonomic activity
Categories: Herb research
Consumption of ephedra (Ma Huang, Ephedrae Herba) extract has both acute and chronic effects on autonomic nervous activity. Twenty healthy Taiwanese subjects were given 1g of ephedra dry extract or placebo once per day for 14 days in a crossover fashion with a seven-day washout period between treatments. Analysis of heart rate variability (HRV) showed that ingestion of ephedra caused the sympathov ...
Nanofibres explain healing properties of yunnan baiyao
Categories: Herb research
American scientists using atomic force microscopy (AFM) have discovered nano-scale fibres in Yunnan Baiyao, the traditional Chinese herbal medicine used to treat wounds. AFM images revealed an abundance of uniform nanofibres, about 25nm in diameter and 86-726nm in length, in a solution of Yunnan Baiyao powder. The authors suggest that the unique adhesive and structural properties of nanofibres may ...
Herbal extract protects neurones
Categories: Herb research
A compound extracted from a Chinese herb traditionally used in the treatment of cancer has been shown to have potent neuroprotective activity. Gambogic amide, derived from the resin of the Garcinia hanburryii tree (known as gamboge or tom rong), provides protection by mimicking the behavior of nerve growth factor (NGF). Both molecules bind to neuronal TrkA receptors and trigger activation of numer ...
'Dragon's blood' kills stomach ulcer bug
Categories: Digestive & Bowel disorders, Herb research
Researchers in China have identified the active ingredients of 'dragon's blood', a resin derived from the herb Xue Jie (Draconis Sanguis), which are responsible for its beneficial effects on peptic ulcers and ability to stop bleeding. Twenty-two different compounds identified from the powdered stems of the plant were tested for effects on Helicobacter pylori (H. pylori), the bacterium known to cau ...
