Great Mullein (Verbascum thapsus) and Inflammation (general): evidence and sources

Common mullein (Verbascum thapsus L.) is a medicinal plant readily found in roadsides, meadows and pasture lands and has been used to treat pulmonary problems, inflammatory diseases, asthma, spasmodic coughs, diarrhoea and migraine headaches. Although it has been used medicinally since ancient times, the popularity of common mullein has been increasing commercially for the past few years. Today, the dried leaves and flowers, swallow capsules, alcohol extracts and the flower oil of this plant can easily be found in health stores in the United States. The use of common mullein extracts in folk medicine begun recently to be supported by an increasing number of research studies. This paper thoroughly reviews all the scientific research related to Verbascum thapsus L. including plant tissue cultures and the biological properties of this plant.

Medicinal plants represent rich sources of traditional medicines and numerous currently used medicines are either directly or indirectly derived from plants. Verbascum thapsus L. (great mullein or common mullein), a medicinal herb indigenous to northern Africa, western and central Asia, and Europe, has been brought to the Americas and Australia. It has been used as a medicine for lung, skin and throat disorders and has a long history of therapeutic importance, particularly as an astringent and calming agent. Presently, the dried leaves, flowers, various plant extracts and flower oil are used in several formulations within Indian traditional medicine. An extract taken from the roots is useful in minimizing toothache, and it also relieves stiffness and seizures. V. thapsus contains a wide variety of phytoconstituents, such as flavonoids, iridoid, phenylethanoid and phenylpropanoid glycosides, saponins, as well as vitamin C and minerals. The most valuable constituents are coumarin and hesperidin, which possess healing properties. Emerging literature based on experimental studies on V. thapsus demonstrates various biological and pharmacological properties, including antiviral, antioxidant, analgesic, sedative, anti-inflammatory, hypnotic, antibacterial, antifungal, as well as anticancer activities. The present review provides an updated, comprehensive, and critical evaluation of various health-promoting and disease-mitigating properties of V. thapsus.

Verbascum species (common mullein) have been widely used in Spanish folk medicine to treat pathologies related to the musculature, skeleton, and circulatory, digestive, and respiratory systems, as well as to treat infectious diseases and organ-sense illnesses. These applications support the potential anti-inflammatory action of Verbascum phytochemicals. Based on the aforementioned facts, and following a deep bibliographic review of the chemical composition of the 10 species of Verbascum catalogued by the Spanish Inventory of Traditional Knowledge related to Biodiversity, we look for scientific evidences to correlate the traditional medical uses with the chemical components of these plants. To support these findings, in silico simulations were performed to investigate molecular interactions between Verbascum phytochemicals and cellular components. Most of common mullein traditional uses could rely on the anti-inflammatory action of phytochemicals, such as quercetin, and it could explain the employment of these plants to treat a wide range of diseases mediated by inflammatory processes such as respiratory diseases, otitis, arthrosis, and rheumatism among others.

Background The pain and discomfort caused by episiotomy affect the quality of life of the mothers, so rapid and complete repair of the episiotomy is very important. Due to the effective ingredients of Verbascum Thapsus, it has been used since ancient times to treat wounds. Therefore, this study aimed to evaluate the effect of Verbascum Thapsus on episiotomy wound healing. Methods The study was designed as a randomized, double-blind, controlled clinical trial. Ninety-three primiparous women who were referred to Fatemeh Zahra Hospital in Saveh in 2015 were randomly divided into two groups of intervention (Verbascum Thapsus) and control (placebo). Both groups covered the episiotomy wound twice a day for 10 days with 2 cm of prescribed creams. Wound healing was assessed using the REEDA scale before the intervention and on days 1,3 and 10 after the intervention. Results Before the intervention, there was no statistically significant difference in terms of demographic characteristics, obstetrics, and REEDA scores between the two groups (p Conclusions According to the results of this study, it seems that Verbascum Thapsus is effective in repairing episiotomy wounds. The researchers hope that the results of this study can provide clinical evidence for the use of this herbal medicine in the wound healing process. Trial registration This study was registered in the Iranian Registry of Clinical Trials (IRCT) with the code " IRCT201404073106N15 " on 02/12/2015.
