[edit] Medical Usage
It has been considered a tonic and diaphoretic (1,5,9,22,27,32,44,51,58,63,68,73,84). In large doses it acts as an emetic and cathartic (5,22,32,40,51,58,63,68). It has been used as a laxative (22,38,68). It has also been used as a purgative (5,22,63). The Indians and early settlers considered boneset a panacea (40). The dried leaves were official with the prescribed dose of two grams (2).
[edit] Symptoms
The American Indians used the tea to combat fevers (5,19,22,27,32,36,51,54,63,74). The tea has been used to treat coughs and consumption (27,36,38,84). The tea has been used for rheumatism (1,19,22,27,54), arthritis and gout (63). Chiefly, the herb tea has been used for fevers (5,32,36), colds and flu (1,19,22,27,51,54,63,84). Creek Indian women that complained of aches and pains in the hips, boiled boneset and steamed the hip area for relief (36,63). It has been used for dyspepsia and general debility (5,19,22,32,38,68). In the late 1700's, it was used to treat yellow fever (63). The American Indians used it to heal broken bones (27).
[edit] Biological industrial uses of this plan
Bees utilize this plant for honey (92,93).
[edit] Chemistry information about this plan
It contains the bitter glucoside, eupatorin (58,84). Recent experiments have shown the presence of four sesquiterpene lactones euperfolin, euperfolitin, eufoliatin, and eufoliatorin, which have cytotoxic and antitumor activity (28).
[edit] Personal experimentation and use of this plant by Thomas A. Naegel
I took one ounce of the dried leaves, poured one quart of boiling water over them and let it steep for ten minutes. I drank the quart within one hour; the taste was very bitter and I noticed a slight diaphoretic effect.
