Medicinal use of Hu Huang Lian:The dried rhizome is antibacterial, anti-inflammatory, antiperiodic, cathartic (in large doses), cholagogue, laxative (in smaller doses), stomachic and bitter tonic. The root contains a number of very bitter glucosides including kutkin and picrorhizin. It also contains apocynin, which is powerfully anti-inflammatory and reduces platelet aggregation. In trials, the rhizome was shown to boost the immune system and to have a specific action against the parasie Leishmania donovani, which causes the tropical parasitic disease called leishmaniasis. The rhizome has a very beneficial effect upon the liver and digestive system and is used in the treatment of a wide range of conditions including fevers, constipation, dyspepsia and jaundice. It is also often used in the treatment of scorpion stings and snake bites. There is also some evidence that the rhizome can be of help in the treatment of bronchial asthma and a number of auto-immune diseases such as psoriasis and vitiligo, whilst it has also been shown to reduce blood cholesterol levels and reduce coagulation time. The rhizome is gathered in the autumn and dried for later use.
