Dang Gui Yin Zi is used to treat Blood Deficiency with External Wind
It's important to remember that herbal formulas are meant to treat patterns, not "diseases" as understood in Western Medicine. According to Chinese Medicine patterns, which are disruptions to the body as a system, are the underlying root cause for diseases and conditions.
As such Dang Gui Yin Zi is mostly used to treat the pattern "Blood Deficiency with External Wind" which we describe below.
But before we delve into Blood Deficiency with External Wind here is an overview of the Western conditions it is commonly associated with:
Urticaria Eczema Psoriasis Contact dermatitis Drug rash Diaper rash Neurodermatitis Ichthyosis Rashes Measles Radiotherapy for breast cancer Alopecia Carbuncles Furuncles Drug-induced dermatitis Pruritis associated with AIDS
Again it wouldn't be correct to say "Dang Gui Yin Zi treats urticaria" for instance. Rather, Dang Gui Yin Zi is used to treat Blood Deficiency with External Wind, which is sometimes the root cause behind urticaria.
Now let's look at Blood Deficiency with External Wind, a pattern that TCM practitioners commonly treat with Dang Gui Yin Zi.
