1250 Elsholtzia. Named by Willdenow, in memory of a Prussian botanist, John Sigismund EJshoItz, who 
lived in the middle of the seventeenth century. Inconspicuous hardy herbaceous plants of little merit. 
1251. Lavandula. From lavare, to wash. The use of the distillod water of this plant is well known. 
The flowers of L. spica have an agreeable fragrant odour, and warm bitterish taste. Alcohol extracts their 
virtues completely, and elevates in distillation all their odorous parts ; water acts less completely. The oil, 
however, on which their virtues depend, is obtained separate in distillation with water ; in the proportion, 
according to Lewis, of one ounce of oil from sixty ounces of the flowers. Lavender is stimulant and tonic. 
The oil extracted by alcohol enters into several compositions. The dried leaves in powder were used formerly 
as a sternutatory ; but they are now neglected. The flowers are cut in dry weather, when they begin to blow.
