In conclusion, our findings suggest that flavonoid fraction (MAF) and luteolin (0.5% w/w) may have potential benefit in enhancing wound healing in diabetic condition, possibly due to free-radical scavenging activity of plant.

BackgroundBambusa vulgaris (Family: Poaceae) used in Ayurveda for paralytic complaints, inflammatory disorders and externally to skin disorders. It has various medicinal uses with good nutritional composition and a rich source of vitamins, proteins, amino acid, beta-carotene and phenolic compounds.ObjectiveThe present study was aimed to evaluate wound healing and anti-inflammatory potential of ethanol extract of B. vulgaris leaves in rats.Materials and methodsThe B. vulgaris leaves were evaluated for wound healing on incision and excision wound methods. Anti-inflammatory effect was evaluated by measurement of paw edema in carrageenan-induced inflammation in rats. Ethyl acetate (BVL-A) and aqueous (BVL-B) fractions from the ethanol extract of leaves were screened for wound healing effects by measuring tensile strength and biochemical parameters in incision wound method. The wound contraction area, antioxidant status and histopathological studies were done in excision wound method.ResultsTensile strength and hydroxyproline level of 5% w/w ointment of BVL-A and BVL-B treated groups were found significantly (P < 0.01) higher and comparable to the reference group. The histopathological study showed the proliferation of collagen, fibrous tissue, and capillaries with epidermal covering at the margin of the wound. The percent inhibition of paw edema was significantly decrease by increasing concentration of BVL-A and BVL-B fractions. In addition, it was found that B. vulgaris possesses antioxidant properties, by its ability to increase antioxidants level.ConclusionsThe results obtained in the present study were indicated that ethyl acetate fraction of B. vulgaris leaves inhibits paw edema and accelerates cutaneous wound healing.

Marrubium vulgare L. (family: Lamiaceae), also known as the white horehound, is widely used as an herbal remedy for chronic coughs and colds. It is used in various disorders related to skin, liver, gastric, heart, and immune system. This review abridges phytochemical, pharmacological studies, and medicinal uses of M. vulgare and provides scientific proof for various ethnobotanical claims to identify gaps, which will give impulsion for novel research on M. vulgare based herbal medicines. This review summarizes selected scientific evidence on phytochemistry and pharmacological properties of M. vulgare over the past 48 years . Works related to M. vulgare was reviewed from various sources such as books, internet source, i.e., Google Search engine, PubMed, and Science Direct, and chemical abstract. The exhaustive literature was studied, and critical analysis was performed according to their phytochemical and pharmacological properties. Phytochemical investigations on different parts of M. vulgare have been reported the presence of flavonoids, steroids, terpenoids, tannins, saponins, and volatile oils (0.05%). The aerial parts contain marrubiin, together with ursolic acid and choline. Pharmacological activities such as antinociceptive, antispasmodic, antihypertensive, antidiabetic, gastroprotective, anti-inflammatory, antimicrobial, anticancer, antioxidant, and antihepatotoxic activity have been reported. M. vulgare has therapeutic potential in the treatment of inflammatory conditions, liver disorders, pain, cardiovascular, gastric, and diabetic conditions. Aerial parts of M. vulgare is a good source of labdane type diterpene especially marrubiin which is present in high concentrations. However, further scientific studies are needed to explore clinical efficacy, toxicity and to explore the therapeutic effect of major secondary metabolites such as diterpenes, phenylpropanoid, and phenylethanoid glycosides of M. vulgare.
