“…Compound 1 had an SI value >2.02, and thus potentially has selective toxicity for TB whereas compound 2 with SI value of less than 1 suggests that the compound may be more toxic for mammalian cells than for TB, hence, it has no selective toxicity. Other previous studies of Eucalyptus species have reported on the antimicrobial (Oyedeji et al, 1999;Delaquis et al, 2002;Sartorelli, 2007) and anti-mycobacterial (Sherry & Warnke, 2004) activities of the Eucalyptus essential oils. There are very few reports on the antimicrobial activities of Eucalyptus extracts (Babayi et al, 2004;Adeniyi et al, 2009a,b;Cock, 2009), and to the best of our knowledge no report so far on the anti-mycobacterial activity of Eucalyptus extracts.…”

“…and E. torelliana F. Muell have been used for the treatment of coughs associated with TB and other forms of respiratory tract infections. The essential oils of E. camaldulensis and E. torelliana have been reported to have antimicrobial activities (Oyedeji et al, 1999). E. camaldulensis is a folk remedy for colds, colic, coughs, diarrhea, dysentery, hemorrhage, laryngalgia, laryngitis, pharyngitis, sore throat, spasm, trachalgia, and wounds.…”

“…In other studies, the NPs offered improved properties to essential oils; Scandorieiro et al showed oregano essential oil plus Ag NPs had synergic effect against all 3 extended spectrum beta-lactamase (ESBL)-producing E. coli and this combination had bactericidal activity (21). The antibacterial activity of the eucalyptus oil was shown in different studies (22)(23)(24)(25)(26).…”

Background: Notwithstanding the current advances in the drug discovery and the pharmaceutical biotechnology, the bacterial infectious diseases are still one of the biggest health concerns worldwide. Also, the new therapeutic methods are urgently required due to the increasing resistance to antimicrobial agents. Objectives: The current study aimed at investigating the synergic effect of eucalyptus leaf oil and silver nanoparticles (Ag NPs) on Escherichia coli H7:O157, Escherichia coli, methicillin-resistant Staphylococcus aureus (MRSA), Salmonella enterica, and Bacillus subtilis. Methods: The current experimental study was performed in Islamic Azad University, Iran. The disc diffusion method, well diffusion method, and broth dilution assay were used in the current study. Results: Results showed that none of the drugs affected the bacteria by disk diffusion method. In broth dilution method, E. coli O157:H7, E. coli, MRSA, and S. enterica showed the same susceptibility and B. subtilis showed more susceptibility to the combined agents. Conclusions:The current study showed the synergic effect of Ag NPs 1.5 ppm plus eucalyptus leaf oil on the growth inhibition of E. coli O157:H7, E. coli, MRSA, S. enteric, and B. subtilis. The combined drug showed more efficiency; lower dose of each medicine in the combinatory form decreased the toxicity in the treatment of infections caused by these bacteria.

“…It is also fever palliative and putative, hypoglycemic and anthelmintic plant (Ministry of health and medical education, 2004; Zargary, 1996). Eucalyptus plant contains a compound called 1, and 8 cineole or Eucalyptole that is the main composition of this plant (Mulyaningsih et al, 2010;Oyedeji et al, 1996). Artemisia has astringent property, disinfectant activity, antimicrobial, antiparasite, anti-poisoning, and anti-insect effects (AliAbadi et al, 2010;AzadBakht, 2003).…”

Concise review: Medicinal plants are effective against leishmaniasis

et al. 2017

Leishmaniasis is an important zoonotic parasitic disease in tropical areas. It is a neglected disease and is a great health catastrophe in Iran. Pentavalent antimony compounds are used for its treatment, but they have adverse effects. Therefore, the use of natural herbs with low adverse effects seems necessary for treatment of Leishmaniasis. In this study, we tried to introduce the natural medicines effective against Leishmaniasis. In this review study, keywords searched included natural medicines, herbal medicines, medicinal plants, Leishmaniasis, and treatment in relevant publications published between 1990 and 2017. Searching was on databases including ISI Web of Science, PubMed, PubMed Central, Scopus, ISC, SID, Magiran and some other databases. The relevant articles were reviewed for the review study. The results showed that medicinal plants: Ferula assafoatida (with IC50 of 0.38 mg/ml), Glycyrrhiza glabra (with IC50 of 25mg/ml), Allium sativum (with IC50 of 0.57 mg/ml), Cephalis ipecacuana (with IC50 of 0.01 mg/ml), Artemisia aucheri (with IC50 of 0.46 mg/ml) and Eucalyptus globulus (with IC50 of 0.17 mg/ml) were the natural medicines effective against the disease.
