Comment:
1. The Chinese Dittany Bai Xian Pi (root bark of D. dasycarpus) is Cold, dry, and Bitter. It is used primarily to clear Heat and Poison; used for Sores, Carbuncles and Rashes associated with Damp-Heat (red sores with lots of pus), including those associated with Wind (with itching). It is also used for Damp-Heat vaginal discharge with Pruritis. It is also classically used for Jaundice and Joints disorders.
2. Dictamnus dasycarpus has been given as a synonym of D. alba by some sources (The Plant List). Even the Chinese name of the herb Bai Xian represents the White (Bai) form of Dittany. The uses are similar, and while Western writers regard Dittany as Warm, the Chinese view it as Cold. Despite this, it also ‘mobilizes the Blood’, which perhaps explains its regard of being Warm in the West, as well as its Emmenagogue uses.
3. Western writers regarded White Dittany as being capable of inducing abortion, making it forbidden for use during Pregnancy. Interestingly, Chinese sources do not regard it as contraindicated during Pregnancy. This suggests the Blood-moving effects of the Western variety to be superior. Nevertheless, there is enough similarity in appearance, general uses and chemical composition to regard the Western and Chinese varieties as fairly synonymous in effect, especially when used in Traditional formulas. The fact that the plant has shown toxicity in susceptible individuals suggests it is wise to avoid during Pregnancy.
