Botanical Name Saussurea lappa (syn. Aucklandia lappa) (Official)
Sources for Costus (Mu Xiang) are varied and complex; alternate species used include: 1. Inula helenium, I. racemosa (Tu Mu Xiang; used in India) 2. Jurinea souliei (Chuan Mu Xiang; used in Sichuan, China) 3. Vladimiria souliei (Chuan Mu Xiang) 4. Aristolchia debilis, A. contorta (Ching Mu Xiang); no longer used due to its toxicity.
Arabian, Bitter and Sweet varieties were traditionally known in the West, but only the Arabian (S. lappa) was commonly available in Europe, and was regarded as best. The Arabian is heavy, ashen colored, hard to break, with a strong smell and aromatic taste and a little bitterness. The varieties available in the West included: 1. Arabian, White, Sweet, or Ancient Costus: Saussurea lappa (best) 2. Indian, Black, or Bitter Costus: Inula racemosa (some sources say Orris) 3. Syrian Costus: heavy, dark with an overpowering scent (lowest quality)
Tibetan Medicine also recognises a 'White' (Vladimira) and 'Black' (Saussurea) type of Costus.
Some authorities (Dymock, Pharmacographia Indica, 1893; Khare, Indian Herbal Remedies) have stated Sweet Costus of the Arabs is Orris root (Iris germanica) which is also listed in Hamdard (Unani) publications.
