237. Oelastrus scandens. False bittersweet; wax work. This 

 plant is extensively used in the form of ointment, as an excellent 

 discutient in all indolent indurations, and swellings, both acute and 

 chronic ; for cakes in the udders of cows, it has been more exten- 

 sively used than any within my knowledge. I have used it success- 

 fully for prurigo labialis with more relief than any other applica- 

 tion. It is good in burns, and excoriations. It is diuretic, and a 

 decoction of the bark of the roots has been successfully used in 

 strangury and gravel. It is said to be antisyphilitic and emetic.
