Background: Neglected tropical diseases (NTDs) like zoonotic cutaneous leishmaniasis (ZCL), is a widespread infectious disease with high mortality and morbidity. Various medications are used for treating the disease, but several side effects and drug resistance have been reported. Herbal medicines are unlimited sources for discovering new medications to treat infectious diseases. We aimed to determine the leishmanicidal activity of three species of Iranian Artemisia herbal plant extracts in in-vitro. Methods: In-vitro anti-leishmanial activity of ethanolic extracts on both promastigotes and amastigotes was determined by using MTT method. IC50, CC50, EC50 and SI were calculated. The study was done in 2019-2020 in Iran University of Medical Sciences, Tehran, Iran. Results: All of the three Artemisia species significantly reduced the number of parasite promastigotes. Among them, A. persica had the highest leishmanicidal activity against parasite promastigotes. Cytotoxicity assay elucidated that the Artemisia had no toxicity to the host cells, and killed the L. major amastigotes very efficiently. By increasing the dose of extracts, the parasite number in both phases (promastigotes and amastigotes) was reduced significantly. Conclusion: These results indicated satisfactory anti-leishmanial activity of Artemisia extracts against ZCL in-vitro. Accordingly, Artemisia ethanolic extracts might be considered as a strong, effective and safe herbal compound for clearing the L. major with less toxicity to the host macrophages cells. Hence, it may be recognized as an excellent herbal therapy for treating the ZCL.

Artemisia copa var. copa, popularly known as “copa”, “copa-copa”, “coa”, “copal” or “tola”, is an aromatic shrub that inhabits the high Andean peaks and the Puna region of Chile, Bolivia, and Argentina. Its aerial parts are sold in the local markets as a sedative, for the treatment of digestive disorders, hypertension, fever, urinary, respiratory infections, and frictions to relieve rheumatism. The morpho-anatomy and the histochemistry of the aerial parts of a native population of A. copa (Catamarca province, Argentina) were described in order to determine diagnostic characters and to identify the site of synthesis and storage of essential oils and other secondary metabolites. A. copa can be differentiated from other Artemisia species by a set of morpho-anatomical features, such as the presence of entire to segmented leaves; ribbed young stems with circular to quadrangular shape; schizogenous secretory ducts distributed (1–2) near the xylem at the midvein of the leaf and the cortex of the stems; non-glandular two-armed “T” shaped trichomes with 2–4 short uniseriated basal cells and biseriate capitate glandular trichomes. Epidermal cells, glandular trichomes, and secretory ducts were associated with the synthesis and accumulation of essential oil, triterpenic and phenolic compounds. Triterpenes (lupeol, α- and β-amyrin); phytosterols βsitosterol, stigmasterol, campesterol, and 24-methyl cholesta-5, 22-dien-3β-ol); sesquiterpene lactones (leucodin and achillin) and flavones (chrysosplenetin and jaceidin,) were identified in the chloroform extract. The essential oil showed chrysanthenone (76.9%), as the main component, accompanied by minor amounts of other mono- and sesquiterpenoids.

The effectiveness of antimalarial drugs is declining at an ever accelerating rate, with consequent increase in malaria-related morbidity and mortality. The newest antiplasmodial drug from plants is needed to overcome this problem. The aim of this study was to assess antimalarial activity of the ethanolic extracts of 10 different medicinal plants from eight families against Plasmodium falciparum chloroquine-sensitive 3D7 strain. The selection of the hereby studied plants was based on the existing information on their local ethnobotanic history. Plants were dried, powdered, and macerated in a hydroalcoholic solution. Resulting extracts have been assessed for in vitro and in vivo antimalarial and brine shrimp toxicity activities. Of 10 plant species tested, four plants: Althea officinalis L. (Malvaceae), Myrtus communis Linn (Myrtaceae), Plantago major (Plantaginaceae), and Glycyrrhiza glabra L. (Papilionaceae) displayed promising antimalarial activity in vitro (50 % inhibitory concentration values of 62.77, 42.18, 40.00, and 13.56 μg/mL, respectively) with no toxicity against brine shrimp larvae. The crude extracts of three active plants, G. glabra, M. communis, and A. officinalis, also significantly reduced parasitemia in vivo in female Swiss albino mice at a dose of 400 mg/kg compared to no treatment. Antiplasmodial activities of extracts of A. officinalis and M. communis are reported for the first time.
