Ferula assa-foetida has several medicinal properties including anthelmintic, sedative, expectorant, antiseptic, laxative, carminative, analgesic, antispasmodic, and treating asthma and paralysis.

The essential oil was isolated through hydro-distillation for three hours by Clevenger, then its chemical composition was analyzed using GC and GC/MS. Thirty six compounds were identify bitter Asafetida in essential oil representing 94.93% of the total components. The major components were reported Bis (1-methyl–thio) propyl disulfide (29.68%), (Z)-1–propenyl sec–butyl disulfide (19.34%), (E)-1–propenyl sec–butyl disulfide (15.73%), -pinene (8.15%), Z--Ocimene (6.09%). 10-epi–– Eudesmol (3.99%) and 4-epi-cis- Dihydroagarofuran (3.11%). Twenty two compounds were identified sweet Asafetida in essential oil. It was included 94.05% of the total components. (E)-1–propenyl sec–butyl disulfide (30.45%), 1- (propylthio)-propyl propyl disulfan (22.68%), %), (Z)-1–propenyl sec– butyl disulfide (18.68%), Tetrahydro-2-ethyl thiophen (7.14%), Bis (1-methyl–thio) propyl disulfide (5.07%) and Methyl tert-butyl sulfide (3.94%) are presented as major components. Twenty two compounds were identified in Asafetida in essential oil consumed in India which included 99.91% of compounds. Bis (1-methyl–thio) propyl disulfide was the major component (44.43%), then (E)-1–propenyl sec–butyl disulfide (25.73%), (Z)-1–propenyl sec– butyl disulfide (19.71%) and 1–propenyl sec–butyl disulfide (4.16%) were the other main compounds.
