Iridoids Isolation from a Phytochemical Study of the Medicinal Plant Collected in Iraqi Kurdistan.

Herbal medicines are still widely practiced in Kurdistan Region-Iraq, especially by people living in villages on mountainous regions. Among plants belonging to the genus (family Lamiaceae), which are commonly employed in the Kurdish traditional medicine, we have analyzed, for the first time, the methanol and aqueous methanol extracts of aerial parts. The plant is mainly used by Kurds to treat jaundice, liver disorders and stomachache.

Bio-Active Compounds from Plants Used in the Traditional Medicine of Kurdistan Region, Iraq.

Acaricidal Efficacy of Plants from Ecuador, (Asteraceae) and (Lamiaceae) against Larvae and Engorged Adult Females of the Common Cattle Tick, .

Control measures against common cattle tick are of the upmost importance because of considerable, deleterious impact on a farm's economy. Due to resistance phenomena to synthetic acaricides being a constraint in affected farms, the search for plant derivatives as acaricides has increased dramatically in recent years. In this work, essential oils obtained from two Ecuadorian plants, and (EO, EO), traditionally used as insecticides in indigenous communities, were studied on larvae and engorged females at the parasitic stages of .
