sembling the pitch-tree in appearance, and with a diminutive 
purple blossom. A decoction of the root, taken in doses of 
one hemina, carries off the bilious and pituitous secretions by^^ 
stool, and a spoonful of the seed, used as a suppository, has a 
similar effect. A decoction of the leaves in vinegar removes 
scaly eruptions of the skin ; and in combination with boiled 
rue, it effects the cure of diseases of the mamillse, gripings in 
the bowels, wounds inflicted by serpents, and incipient gather- 
ings of most kinds. 
CHAP. 22. — EESINS : TWENTY-TWO EEMEDIES. 
In treating, first of wines,^^ and then of trees, we have 
Stated that resin is the produce of the trees above-mentioned, 
and have described the several varieties of it, and the countries 
in which they are respectively produced. There are two 
principal kinds of resin, the dry and the liquid.^^* The dry 
resins are extracted from the pine^^ and the pitch- tree,^* the 
liquid from the terebinth,^^ the larch, the lentisk,^^ and the 
cypress these last producing it in the province of Asia and 
in Syria. It is an error ^ to suppose that the resin of the pitch- 
tree is the same as that of the larch ; for the pitch- tree yields 
an unctuous^ resin, and of the same consistency as frankin- 
cense, while that of the larch is thin, like honey in colour, and 
of a powerful odour. It is but very rarely that medical men 
make use of -liquid resin, and when they do, it is mostly that 
produced by the larch, which is administered in an egg for 
The characteristics of it differ, however, from the description here given 
by Pliny. It is no longer used in medicine, though, like the other Euphor- 
biacese, it has very active properties. 
This, Fee says, is consistent with truth.

Or, as they are called at the present day, the resins, and the oleo- 
resins, or terebinthines. 
9* Fee thinks that this name extends to the numerous species of resin- 
iferous trees. 9^ The Abies excelsa of Linnaeus. 
96 The Pistacia terebinthus ; see B. xiii. c. 12. It yields a valuable 
turpentine, known in commerce as that of Cyprus or Chios. 
9"^ The so-called Venice turpentine is extracted from the larch. 
98 It yields mastich solely, a solid resin. 
99 It yields a terebinthine, and a very diminutive amount of solid resin. 
1 Fee says, that if the same methods are employed, the same products 
may be obtained, though in general the larch yields the better terebinthine. 
2 Fee thinks that he is speaking of a thick resin, or gali2)otj as the 
French call it, of the consistency of honey.
