Angelica acutiloba
Also called Japanese Angelica Root
Acutelobed Angelica is a perennial herb from Japan, grown mainly for its medicinal root (tōki) in Kampō medicine. It thrives in cool, moist, fertile soil with some sun or partial shade.
Angelica acutiloba is a perennial herb from the family Apiaceae or Umbelliferous (carrot or parsley family). It is predominately in Japan and perhaps endemic (unique). It is now distributed widely and cultivated in Jilin, China, Korea, Taiwan and Indonesia.
The common name of Angelica acutiloba is known as tōki (トウキ, 当帰) in Japanese. The root was used as a substitute for the crude drug tōki (当帰) in Kampō medicine (漢方製薬 Kanpō Seiyaku), which is a Japanese adaptation of Traditional Chinese medicine.
A. acutiloba grows in moist clay soils. It prefers sunlight, but can grow in shady woodland. Cool climate is suitable for its optimal cultivation. The sowing season is usually the spring during March and May. The plant may be affected by a variety of diseases. As a result, the leaves may wilt or become yellow. Pests like aphids, worms and mites may affect the plant growth as well.
Cold temperature, water and sunlight are preferred for seed germination. In the spring, the seeds may germinate slower than in winter because of the warmer temperature. In some cases, the seeds of A. acutiloba are sown in the first winter and moved to their permanent position at the beginning of next spring for their best germination.
The extract of A. acutiloba roots contains many chemical constituents. It may contain about 2% volatile oils, such as ligustilide, n-butylidenephthalide, folic acid, linoleic acid, safrole, and isosafrole.
