Safety Overview
1.Angelica — Plant Snapshot
Angelica acutiloba, commonly known as Angelica or Japanese Angelica, is a robust perennial herb belonging to the Apiaceae family, a diverse group recognized for its aromatic members. Native to the mountainous and forest regions of East Asia, particularly Japan, China, and Korea, this species thrives in cool, moist, and partially shaded environments. The plant typically reaches an impressive height of 1 to 2 meters, distinguished by its hollow, purplish-green stems.
Its large, bright green leaves are tripinnately compound, featuring lanceolate leaflets with serrated margins, creating a delicate, fern-like appearance. During the mid-summer months, Angelica produces striking compound umbels composed of numerous small, creamy-white flowers. These inflorescences are highly attractive to a variety of pollinators, contributing to the plant's ecological role.
The most pharmacologically significant part of Angelica acutiloba is its thick, fleshy taproot, which is characteristically aromatic with a slightly bitter taste. These roots are optimally harvested in the autumn, typically after two to three years of growth, allowing for the full development of their complex array of bioactive compounds. This careful cultivation and harvesting process ensures the potency of the roots, which are highly prized in traditional East Asian medicinal systems like Traditional Chinese Medicine (TCM) and Japanese Kampo medicine, where it is often referred to as 'Dong Quai' or 'Tohki'.
