However, the parent plant of this ‘resin is still unascertained. 
Elemi is brought here from the Spanish West Indies; it is most 
esteemed when softish, somewhat transparent, of a pale whitish 
colour, inclining a little to green, and of a strong, though not 
unpleasant smell. 
Its use is confined to ointments and plasters. 
Gambogia (gummi resina) Pharm. Lond. & Edinb. 
BY the industry of Koenig, a physician who resided many years 
at Tranquebar, it has been lately discovered that the genuine Gam- 
boge is the concrete juice of a tree which constitutes a new genus, 
under the name Stalagmitis (Schr. Gen. 1585). It belongs to the 
class Polygamia moneecia, and is fully described by Professor Murray 
in the Comment. Gotting. (9. p. 175.) and App. Med. Vol. 4. 
The Cambogia gutta of Linnzus, according to Koenig, also 
affords a yellow juice; but this, on drying, acquires a brownish 
hue, and is considered as a spurious kind of Gamboge. 
Gamboge is brought from the East Indies, and is well known to 
operate powerfully both upwards and downwards, Geoffroy says, | 
that its emetic tendency is counteracted, if given in combination 
with mercurius dulcis, and that it may be given with less danger 
from its, violence, in a liquid form than in substance. In hydropie 
cases it is often used to quicken the operation of other purgatives. 
Though the ordinary dose of this cathartic is two or three grains, 
yet for the expulsion of the tape worm it has been given, with an 
es quantity of sesenble alkali, to the extent of fifteen grains.
