Ma-yo {3fudar, Hind.).

 lobes. 



Yields the ' !Mudar ' root. The fibre is strong and the charcoal excellent for 

 gunpowder. The bark of the roots is a good substitute for Ipecacuanha. "The 

 bark ' of the root of this plant is the best and most useful part for medicinal 

 purposes, and it should be selected fi'oni the oldest plant, because the older it is, 

 the more active is its bark. If the bark be powdered by simply drying it, as is 

 generally done, it requires to bo used in much larger doses, to produce its proper 

 effects. The thick rough and spongy epidermis which it is covered with, and which 

 is quite inert, should be scraped off with a knife before it is powdered. The powder 

 prepared with this precaution is white, and bears a great resemblance to the flower 

 of rice, has an acrid and nauseous smell and bitterish taste." The dose of tliis 

 powder is from 40 to 50 grains, and it is an excellent substitute for Ipecacuanha, 

 especially in dysentery, combined with tincture of opium.
