ABSTRACT
Abstract Several species of thymus have therapeutic properties, so they are used in traditional medicine. In this work was carried out to synthesize Thymus vulgalis silver nanoparticles (TSNPS) and evaluate antioxidant and antimicrobial activities of TSNPS and T. vulgalis essential oil extract (TEOE). The essential oils analyzed by GC-MS and were characterized. Major compounds of phenol, 2 methyl 5 (1 methylethyle) (CAS), thymol and 1,2 Benzene dicarboxylic acid, 3 nitro (CAS) (48.75%, 32.42% and 8.12%, respectively) were detected. Results demonstrated that the TSNPS gave a highest DPPH radical scavenging activity, it was obtained 97.2 at 1000 ug/ml. TSNPS, Thymus + Hexane (T+H), Thymus + Ethanol (T+E) gave the greatest antimicrobial activity than amoxicillin (AM) and ciprofloxacin (CIP). In conclusion: The essential oil of thymus (Vulgaris) and thymus (Vulgaris) silver nanoparticles can be a good source of natural preservatives as an antioxidant and antimicrobial agents for increasing the shelf life of foodstuffs.

BACKGROUND: Cupping (Hijamah) therapy is very well documented as a result of several thousand years of clinical experiences in Unani medicine. In this procedure, suction is created by various means either with or without bloodletting. Though this therapy is being widely practiced across the globe for treating many chronic and intractable ailments but many reports reveal its unscientific and improper practices which results in many complications. Therefore to develop standard operative procedures and to propose protocols of cupping therapy in various diseases is the need of hour. MATERIALS AND METHODS: A thorough literature review of relevant journals and textbooks was performed to gather the maximum available data on cupping therapy. CONCLUSION: This paper seeks to introduce the general concepts of cupping therapy in Unani medicine and other traditional systems of medicine, shortcomings and limitations of the currently published studies and suggest ways to improve these technical/methodological flaws. In addition, the authors have also attempted to provide the cupping related materials, hypotheses, observations which will provide the researchers the base for evaluating their usefulness in future clinical trials.

Leeches are a class of segmented invertebrates, known for their blood-feeding habits and used in phlebotomy to treat various ailments since antiquity. In Europe, medicinal leeches have recently been rediscovered and are used by maxillofacial and other microsurgeons to aid salvage of compromised venous engorged tissue and amputations, such as digits, ears, and nasal tips. Because of their important salivary components, blood-sucking (sanguivorous) leeches, such as Hirudo medicinalis and related species, have engendered great interest from pharmaceutical companies searching for anticoagulants to prevent blood clotting during microsurgeries. Scientific research reveals that the beneficial effects of leeching, in addition to decongestion, include injection of a cocktail of several medicinally useful bioactive molecules present in their saliva. Owing to its therapeutic potential, the research is continuing as many new salivary compounds are being isolated and synthesized.
