The aim of this study was to test antimicrobial activity of ethanol extract of Lavandula stoechas against 22 bacteria and 1 yeast. Also, biochemical composition of the extract was investigated. A wide range of Gram-positive, Gram-negative microorganisms, and multidrug resistant bacteria were selected to test the antimicrobial activity. As a result, the extract is observed to contain fenchone (bicyclo[2.2.1]heptan-2-one, 1,3,3-trimethyl-, (1R)-) and camphor (+)-2-bornanone) as major components and showed antimicrobial activity against all studied microorganisms except Escherichia coli ATCC 25922 and Klebsiella pneumoniae. The results of the study present that L. stoechas is active against MDR strains too.

Many plants contain active substances that are known to be effective in both enhancing the wound healing process and lowering the incidence of wound infections. Previous studies have shown that bryophytes produce a variety of secondary metabolites that present pharmaceutical activities including antimicrobial activity against various pathogenic bacteria and fungi. The aim of this study was to investigate the antimicrobial activity of Mnium stellare against 17 bacterial and 1 fungal strains. Our present study has shown that the ethanol extract of M. stellare has antimicrobial activity against several Gram positive and Gram negative microorganism tested, but its antimicrobial activity is notable especially against B. subtilis, S. typhimirium, S. aureus, S. carnosus, and S. epidermidis. These results are the very first report of the antimicrobial activity of M. stellare.

The use of plants as therapeutic agents have been known since the ancient times. In developing countries, traditional medicinal plants are critical for disease treatment. Various herbal drugs are obtained from these plants for therapeutic use. These herbal drugs are used in the treatment of many diseases from diabetes to cancer. Today, cancer is one of the most important life-threatening diseases for human. Some of the methods used in the treatment of cancer include herbal sources. The scientific world is not oblivious to many herbal drugs used for cancer in traditional treatment methods. Due to the limited effectiveness of drugs, an increasing number of studies have been conducted in the last decade to increase the success of cancer treatments. In recent years, the importance given to the herbal drugs used for medicinal purposes and the studies on the medicinal uses of plants have increased in our country. In this review, researches about the herbal drugs traditionally used against cancer by the local people were investigated. As a result of the study, 160 plant taxa and 17 multi-herbal formulas were reported for cancer treatment in Turkish traditional medicine.
