22 L. SYPHILI'TICA (Lin. spec. 1320. Jacq. icon. S. t. 597.) 

 leaves ovate-oblong, acuminated at both ends, unequally ser- 

 rated ; flowers axillary, solitary, forming altogether a long leafy

 Woodv. med. bot. 177. t. 63. Ker. bot. reg. 537. Rapuntium 

 syphiliticum, Mill. diet. no. 2. Gaertn. fruct. 1. p. 152. t. 

 30. Leaves sessile, rather scabrous, decurrent. Flowers blue. 

 Calyx serrately denticulated. Corolla angular, with nearly equal 

 segments, having the keel ciliated, and the palate furnished 

 with 2 gibbosities. The root is the part of the plant directed to 

 be used in medicine ; it resembles tobacco in taste, and is apt to 

 excite vomiting. It derives its trivial name from its efficacy in 

 the cure of syphilis, as experienced by the North American 

 Indians, with whom it was a secret. A decoction is made of a 

 handful of the roots, in 3 measures of water. Of this half a 

 measure is taken in the morning fasting, and repeated in the 

 evening ; and the dose increased till its effects become too 

 violent, when it is intermitted for a day or two. Although the 

 plant is said to cure the disease in a very short time, yet its vir- 

 tues have not been confirmed by any instances in European 

 practice.
