RemarksThe Pharmacopoeia of the People's Republic of China 2020 edition defines the roots of Stephania tetrandra as "Fangji". Its 2000 edition defines that of Aristolochia fangji as "Guangfangji". "Guangfangji" (Radix Aristolochiae Fangchi, Southern Fangchi Root ) is used for expelling wind to relieve pain, reducing fever and inducing diuresis. It is used for damp-heat with pain in the entire body, edema in the lower limb and difficulty in micturition. "Fangji" has the advantage of inducing diuresis and "Guangfangji" has the advantage of expelling wind. "Hanzhongfangji" is said to be derived from the root of Aristolochia heterophylla. The plants of Aristolochia spp. of family Aristolochiaceae contain aristolochic acid which is known to cause renal damage.
In Japan, "Fangji" is called Boi or, sometimes, Boki.
