Because there is no effective drug therapy for hydatid cyst yet, assessment and finding of some new agents especially from herbal origin with a desired scolicidal effect attracts great attention for treatment and pre-surgical use to prevent the hydatid cyst recurrence. Hazelnut, squash seeds and garlic chloroformic and hydro-alcoholic extracts’ scolicidal effects were examined.
Suspension of protoscolices was obtained from infected liver and or lung of sheep and goats from Ziyaran abattoir. The chloroformic and hydro-alcoholic extracts from hazelnut, squash seeds and garlic were extracted using the succilate method. Scolicidal effect of each extract assessed in different concentrations and effected time using microscopy and 0.1% eosin solution stained only killed protoscolices.
