Artemisia japonica, commonly known as the Japanese wormwood or the Oriental wormwood, is a species of wormwood in the family Asteraceae that is native to Japan, Korea, China, Southeast Asia, and the Indian Subcontinent.[1] Its common name in Japanese is オトコヨモギ, 牡蓬, or otoko yomogi meaning male mugwort in English.[2]
Description
It is a perennial herb growing up to 50-130 centimeters. The rootstock is thick, woody, and has a strong smell. The leaves are clustered at the rounded apex. The leaf blade is spatulate and oblong-obovate to broadly spatulate or flabellate. The achenes are brown and obovoid.[3] The flowering is from August to November.[2] It is most commonly found in the months of August, September, and October. 82.3% of the time it was found it was a preserved sample, and 17.0% of the time it was observed by humans. It is most commonly found in the countries of China, Japan, and Korea.[4]
Artemisia japonica has four varieties:[4]
- Artemisia japonica var. hainanensis native to China.
- Artemisia japonica var. hallaisanensis native to Korea.
- Artemisia japonica var. japonica native to Japan.
- Artemisia japonica var. manshurica native to Northeastern China.
Uses
The young leaves are cooked and eaten. The adult leaves are used as a digestive. A decoction of the leaves can give hypertension if eaten too much. The juice from the plant is used to treat vaginitis and skin diseases.[5] The powder from drying the plant is used as an incense.[6] It is used in making antitoxifying and antifebrile drugs.[7]
In a study about artemisinin production in Artemisia species, A. japonica had around average levels compared to other species (0.05% to 0.15% artemisinin). It also had more artemisinin in the flowers than their leaves.[8]
Ecology
Globodera artemisiae, a parasite, was first found on Artemisia japonica in September 2020. The parasite is commonly found on Artemisia vulgaris.[9] The plant is grazed by sheep and goats in Ladakh and Lahoul, India, but not liked by yaks in the region.[10]
