Koseret

Lippia abyssinica, called koseret in Amharic, is a flowering plant of the verbena family, Verbenaceae. It is endemic to Ethiopia but cultivated throughout tropical African countries. It grows as a shrubby herb about three metres tall at 1600 to 2000 metres altitude, with hairy leaves and small purple or pink flowers. Its other common names include lemon herb, butter clarifying herb and Gambey tea bush, although the last can also apply to Lippia multiflora. The subspecies L. a. var. koseret is dried and used as an herb in Ethiopian cooking, and its smell is camphorous and minty. Wikipedia says the plant has also been used as traditional medicine for cough, fever, constipation and skin conditions such as burns, and as an insecticide and antimicrobial treatment.
