US Dispensatory, 1918.

Tang-kui or Man-mu.—Under the name of tangkui the Chinese have used for a long time a root obtained from some umbelliferous plant closely allied to the Levisticum officinale, which, according to Lezenius (Ph. Centralh., 1910, p. 221), is probably from the Ligusticum acutilobum. A fluidextract of this root has been introduced into European medicine under the name of eumenol and is recommended by a number of authors in the treatment of dysmenorrhea and other uterine complaints. The dose of this fluidextract is one table-spoonful three times a day. Bufalini, having searched in vain for an active alkaloid, believes that the activity of the substance depends upon an ethereal oil.
