SARCOCOLLA (gummi-refina) Pharm. Lond. 
- LINNEUS fuppofes this to be produced by the Pena mucronata, 
an Ethiopian fhrub of the order conglomerate. Others however 
have, in this inftance, doubted his authority, and the fat is ftill 
undetermined. 5 
Sarcocolla is a concrete juice, brought from Perfia and Arabia in 
{mall grains of a paie yellow, having alfo fometimes mixed with them 
a few of a deep red colour. Its tafte is bitter, but followed with fome . 
degree of fweetnefs. It has been chiefly ufed for external purpofes, 
and, as its name imports, has been thought to conglutinate wounds 
and ulcers ; but this opinion now no longer exifts. 
It is an ingredient in the pulvis é ceruffa. 
Rapix INDICA LoPezIANA. Pharm. Edinb. 
THIS root is called after Lopez, a Portuguefe, who, according to 
Redi, found it growing in the province of Zanquebar in Africa; but 
Gaubins ftates it to be a native of Afia, and brought from Goa i in 
Malacca to Batavia. 
To what tree this root is to be referred we have not the means to 
determine. 
_ The root is brought in pieces of eight or nine inches in length, 
and from one to two inches in thicknefs, though generally fmaller, 
confifting of a whitith or ftraw-coloured light wood, having a brownifh 
firm medullary fubftance. Its bark is foft, wrinkled, brown, fome- 
what fpongy, and covered with a thin yellowith epidermis. 
This root, which poffeffes no remarkably fenfible qualities, is re- 
garded i in the Eaft Indies as a medicine of extraordinary efficacy 
in diarrhoeas; and the numerous trials of it, made by Gaubius and 
others, have tended greatly to confirm its reputation. : 
Its dofe, in powder, is from 15 to 30 grains, repeated three or 
four times a day.
