Eleutherococcus is a genus of 38 species [1] of thorny shrubs and trees in the family Araliaceae. They are native to eastern Asia, from southeast Siberia and Japan to the Philippines and Vietnam. [1] 18 species come from China, from central to western parts. [2]
Perhaps the best known in the West is the species E. senticosus used as herbal medicine, [3] and commonly known by such English names as Eleuthero or Siberian ginseng. [3] In Traditional Chinese medicine, this is administered to increase energy, thus traditionally recognized to have attributes akin to true ginseng ( Panax ). [4] [5] This is also reflected in its formerly used genus name Acanthopanax [6] meaning "thorny ginseng". The word "Eleutherococcus," from Greek, means "free-berried."
The European Medicines Agency has concluded that there is insufficient evidence to demonstrate the efficacy of Eleutherococcus for any clinical condition. [7]
The Chinese materia medica in question [3] (Chinese :五加皮; pinyin :wǔjiāpí; Wade–Giles :wuchiapi) may designate a number of species. [8] But the plant now given the common name wujia in China is specifically E. gracilistylus , and according to one source, the genuine crude drug must come from this species, and C. spinosum is only a substitute. [3]
The Japanese name ukogi (ウコギ, 五加(木)) borrows directly from the Chinese name, and refers somewhat broadly to several plants in the genus. [9] A 10th century herbology text, Honzō wamyō (本草和名), introduced the Chinese wujia as an herb to be pronounced mu-ko-gi (牟古岐), refers specifically to E. sieboldianus (Japanese name: hime-ukogi). [10] (See #Species list below).
The taxonomical nomenclature in the botanical science also has had a sinuous history, so that Acanthopanax had been used as the proper genus name in China till recent years, while the West adopted Eleutherococcus as the official name. [3]
Several species are also grown as ornamental garden shrubs. In Japan, they have been planted as hedges. [9] Particularly in Yamagata Prefecture, a daimyō named Uesugi Yōzan [11] encouraged the planting of the ukogi as fencing around the homes of samurai retainers (E. sieboldianus was planted in the region [11] ), and the bitter young buds, leaves and stems have traditionally been picked and eaten as vegetable in the area. However, since the plant is deciduous, it requires sweeping in the fall (high maintenance), and the bare hedges fail to protect the homeowner's privacy.
The four earliest fossil species of Eleutherococcus are from the Maastrichtian (about 70 Ma) floras of Eisleben and Walbeck, Germany, the synonym Acanthopanax is used for these species †A. friedrichii, †A. gigantocarpus, †A. mansfeldensis and †A. obliquocostatus. [12]
The Araliaceae are a family of flowering plants composed of about 43 genera and around 1500 species consisting of primarily woody plants and some herbaceous plants commonly called the ginseng family. The morphology of Araliaceae varies widely, but it is predominantly distinguishable based on its woody habit, tropical distribution, and the presence of simple umbels.
Ginseng is the root of plants in the genus Panax, such as Korean ginseng (P. ginseng), South China ginseng (P. notoginseng), and American ginseng (P. quinquefolius), characterized by the presence of ginsenosides and gintonin. Ginseng is common in the cuisines and medicines of China and Korea.
The Japanese serow is a Japanese goat-antelope, an even-toed ungulate. It is found in dense woodland in Japan, primarily in northern and central Honshu. The serow is seen as a national symbol of Japan, and is subject to protection in conservation areas.
Eleutherococcus senticosus is a species of small, woody shrub in the family Araliaceae native to Northeastern Asia. It may be colloquially called devil's bush, Siberian ginseng, taiga root, eleuthero, ciwujia, Devil's shrub, shigoka, touch-me-not, wild pepper, or kan jang. E. senticosus has a history of use in folklore and traditional Chinese medicine. Root extracts of E. senticosus are sold as a dietary supplement or cosmetic, usually under the name Siberian ginseng.
Angelica sinensis, commonly known as dong quai or female ginseng, is a herb belonging to the family Apiaceae, indigenous to China. Angelica sinensis grows in cool high altitude mountains in East Asia. The yellowish brown root of the plant is harvested in the fall and is a well-known Chinese medicine which has been used for thousands of years.
Adaptogens or adaptogenic substances are used in herbal medicine for the purported stabilization of physiological processes and promotion of homeostasis.

Zanthoxylum ailanthoides, also called ailanthus-like prickly ash, is an Asiatic plant of the prickly-ash genus Zanthoxylum, natively occurring in forest-covered parts of southeastern China, Taiwan, Southeast Asia, and Japan from Honshu southward. The piquant fruit serves as a local substitute for the ordinary red-pepper in China before the Columbian exchange. In Taiwan, the young leaves are used in cuisines.
Incense in China is traditionally used in a wide range of Chinese cultural activities including religious ceremonies, ancestor veneration, traditional medicine, and in daily life. Known as xiang, incense was used by the Chinese cultures starting from Neolithic times with it coming to greater prominence starting from the Xia, Shang, and Zhou dynasties.
