and wounds: A review of tea tree oil as a promising antimicrobial
ABSTRACT Antibiotic-resistant bacteria continue to be a major health concern worldwide. In particular, Staphylococcus aureus, both methicillin-resistant and -sensitive, are of concern in their ability to cause difficult skin and underlying tissue infections. Melaleuca alternifolia oil (tea tree oil), an essential oil, has demonstrated promising efficacy in treating these infections. Tea tree oil has been used for centuries as a botanical medicine, and has only in recent decades surfaced in the scientific literature as a promising adjunctive wound treatment. Tea tree oil is antimicrobial, anti-inflammatory, and has demonstrated ability to activate monocytes. There are few apparent side effects to using tea tree oil topically in low concentrations, with contact dermatitis being the most common. Tea tree oil has been effective as an adjunctive therapy in treating osteomyelitis and infected chronic wounds in case studies and small clinical trials. There is a need for larger clinical trials to further examine efficacy of tea tree oil as an adjunctive wound therapy, as well as improved guidelines for developing plant-based medicines.

ABSTRACT: Tea tree oil (TTO) is the essential oil obtained from the Australian native plant Melaleuca alternifolia. The aim of the current study was to evaluate the possible healing effect of TTO against infectious Alveolitis induced by Staphylococcus aureus (ATCC 6538P) in extracted socket of mongrel dogs. Infection in each alveolus have been induced and treated as the follows: the positive control group, the group treated with tea tree gel, the group treated with tea tree gel + vancomycin hydrochloride, and the group treated with tea tree oil. Histological examinations of the present work revealed that tea tree gel succeeded to promote healing of the extracted sockets and prevented dental alveolitis either alone or in combination with vancomycin. However, the healing effect and antimicrobial activity was pronounced in the animals treated with tea tree gel only followed by combination with vancomycin and finally group treated with tea tree oil.

ABSTRACT: Honey is a natural product obtained from the nectar that is collected from flowers by bees. It has several properties, including those of being food and supplementary diet, and it can be used in cosmetic products. Honey imparts pharmaceutical properties since it has antibacterial and antioxidant activities. The antibacterial and antioxidant activities of Thai honey were investigated in this study. The honey from longan flower (source No. 1) gave the highest activity on MRSA when compared to the other types of honey, with a minimum inhibitory concentration of 12.5% (v/v) and minimum bactericidal concentration of 25% (v/v). Honey demonstrates tremendous potential as a useful source that provides anti-free radicals, anti-tyrosinase and anti-bacterial activity against pathogenic bacteria causing skin diseases.Biological research 01/2015; 48(1):4.
