Physiological Effects. —The general effects of galbanum a re ^; sof the foetid antispasmodic gum-resins already described (p- t j, a nusually ranked between asafcetida and ammoniacum, being weaker ^the fonner, but stronger than the latter. As it yields, by <l istl . ’ llS tmore volatile oil than asafcetida does, it has been su pposed that d ^ u texceed the latter in its stimulant influence over the vascular systeu 1 2 ’ ^as an antispasmodic, it is decidedly inferior to asafcetida. A spec 1 ^mulant influence over the uterus has been ascribed to it: henGermans call it Mutterharz (i. e. uterine resin). . , j^ts,

Uses. —Galbanum is principally adapted for relaxed and torpid jand is objectionable in inflammatory or febrile disorders. It is eI11 P .'.gpin the same cases as asafcetida (p. 1046), with which it is generally 8 llSin combination. It is principally used in chronic mucous or p Jl eJjJ .catarrh, in which it oftentimes proves serviceable. It has also be jployed in amenorrlioea and chronic rheumatism. Externally it 1Sas a mild stimulant, resolvent, or suppurant, in indolent swellings. j„Administration.— It may be given in substance, in the form of P ’

doses of from grs. x. to 5ss., or in the form of emulsion.
