- چکیده:
- چکیده انگلیسی: Skin hyperpigmentation is characterized as increased production and accumulation of melanin, which could be aesthetically unfavorable and develops serious skin diseases. There is a need to find new depigmenting agents, since many current natural and synthetic products present undesired side effects. In Iranian traditional medicine (ITM), plants have been used for the treatment of skin diseases such as hyperpigmentation. In this study, topical herbal medicines, for the treatment of hyperpigmentation were searched in ITM references, and their scientific names were identified, using different comprehensive glossaries. Thereafter, depigmenting mechanisms of these genera were reviewed in recent scientific literatures. Seventy-nine plants were made known as herbal remedies for skin hyperpigmentation. Furthermore, modern literatures have shown depigmenting effect of about 40% of these plants or their isolated compounds, with different melanogenesis inhibitory mechanisms with tyrosinase inhibition as the most revealed method. Regarding the new approach to medicinal plants in recent years, a large number of medicinal herbs that were mentioned in ITM references would be good candidates for exploring new herbal medicines for skin hyperpigmentation disorders.

- چکیده:
- چکیده انگلیسی: Background and objectives: Despite the vast production of new antibiotics in the last three decades, resistance to these drugs by microorganisms has increased and essential oils (EOs) have been recognized to possess antimicrobial properties. Methods: In the present study, EOs obtained from aerial parts of Thymus vulgaris L., Lavandula angustifolia Mill., Rosmarinus officinalis L. and Mentha piperita L., were evaluated for their single and binary combined antibacterial activities against four Gram-positive and Gram-negative pathogenic bacteria: Staphylococcus aureus, Bacillus cereus, Escherichia coli and Pseudomonas aeruginosa. Results: The results exhibited that some of the tested essential oils revealed antibacterial activities against the examined pathogens using broth microdilution method. Maximum activity of the testedessential oils was obtained from the combination of T. vulgaris and M. piperita essential oils against Staphylococcus aureus (MIC= 0.625 mg/mL). Conclusion: Combinations of the essential oils in this study showed synergic action against some pathogenic microorganisms which could be considered in medical and food industries as preservatives.

- کلمات کلیدی: Herbal Medicine,Iranian Traditional Medicine,Halitosis,oral malodor
- چکیده:
- چکیده انگلیسی: Halitosis is an oral health condition characterized by unpleasant odors emanating constantly from oral cavity. Almost 22-50% of the population experiences such a condition during lifespan and about half of them suffer from personal discomfort and social embarrassment. Based on the literature survey, it seems that the oral cavity is the most important origin of halitosis; therefore, this area could be considered as the best target for the treatment. Halitosis is a well-known disorder in Iranian Traditional Medicine (ITM); Avicenna and some other famous Iranian traditional physicians have described this condition in their manuscripts precisely. Herbal therapy was the major treatment suggested by Iranian scholars in which mixtures of medicinal plants were used in the form of mouthwashes and other oral formulations. In the present study, six Iranian ancient medical texts were screened for the herbs with anti-halitosis effects. Subsequent to this study, the medicinal herbs were listed and scored based on the frequency of their repetition. Moreover, the effort has been taken to provide the best scientific name for each plant as well as searching modern studies about their biological effects. In our investigation fourteen plants were obtained as the most frequent herbs for treatment of halitosis in ITM. Previous studies revealed that some of these plants have shown biological activities relating to anti-halitosis effect. The present study introduces some more plants for future studies about anti-halitosis property.

- چکیده:
- چکیده انگلیسی: Burns are known as one of the most common forms of injury with devastating consequences. Despite the discovery of several antiseptics, burn wound healing has still remained a challenge to modern medicine. Herbal products seem to possess moderate efficacy with no or less toxicity and are less expensive compared to synthetic drugs. Burn is a well-known disorder in Iranian Traditional Medicine (ITM). Iranian physicians have divided burns into various types based on the cause and recommended treatment for each type. According to ITM references, herbal therapy was the major treatment prescribed by Iranian physicians for burns. In the present study, seven ancient Iranian medical texts were screened for the herbs with burn healing effects along with their applied dosage forms. The medicinal herbs were listed and scored based on the frequency of their repetition. Moreover, the best scientific name that was suitable for each plant as well as surveying modern studies about their biological effects has been carried out. In our investigation eighteen plants with seven topical application categories have been obtained as the most frequent herbs for burn healing in ITM. Modern studies have revealed that these plants have shown some biological activities such as anti-inflammatory, antimicrobial and antioxidant effects which might establish the relationship between the mentioned activities and burn wound healing property. This list can provide a suitable resource for future researches in the field of burn treatment.
