Ulmaria five Regina prati. Barba capra floribus compactis C. B. Spiraea Ulmaria Linn. Meadowsweet or Queen-of-the meadows: a plant with tall, smooth, reddish, brittle stalks; and oval, sharp-pointed, indented leaves, set in pairs along a middle rib, with smaller pieces between, and at the end a larger odd one divided into three fections, wrinkled and green above, white underneath: on the tops come forth large thick clutters of little whitish flowers, followed each by several crooked seeds set in a roundish. head. It is perennial, common in most meadows, and flowers in June.
The leaves of ulmaria recommended as mild astringents, discover to the taste or smell very little foundation for any medical virtues. The flowers have a strong and pleasant smell, in virtue of which they are supposed to be anti-spasmodic and diaphoretic, and which in keeping is soon dissipated, leaving in the flowers only an insipid mucilaginous matter. As these flowers are more rarely used in medicine than their fragrant smell might rationally persuade, Lin-nasus suspects that the neglect of them has arisen from the plant being possessed of some noxious qualities, which it seemed to betray by its being left untouched by cattle: it may be observed, however, that the cattle, which resused the ul-maria, resused also angelica, and other herbs, whose innocence is apparent from daily experience.
