Objective: The objective of the present research was to investigate the wound-healing potency of solid lipid nano particles of Hibiscus rosa sinensis extract. Crude herbal extracts and rudimentary formulations containing herbal extracts are good for demonstrating the feasibility of the concept; however, such formulations suffer with poor oral bioavailability and variability within groups of subjects. Converting herbal extracts into novel drug delivery systems may prove effective in addressing some of these problems. Methods: In the present study an attempt was made to develop Hibiscus rosa sinensis extract loaded solid lipid nanoparticles (HSLNs) using lipids glycerol monostearate (GMS) or beeswax. The prepared HSLNs were characterised for their size, surface charge and morphology. The optimized HSLNs were incorporated into Carbopol gel and tested for wound healing activity in male Wistar albino rats using excision wound model. Results: HSLNs of ~175 nm in size carrying negative charge were obtained with the optimised procedure using beeswax. The shape of the HSLNs was nearly spherical. The HSLNs (10 mg/ml) treated wounds healed much faster compared to raw crude extract and healing was comparable to marketed preparation. Conclusion: It is concluded that converting crude herbal extracts into SLNs can be an effective way to enhance the effectiveness of herbal extracts and their in vivo activity.

Mediterranean-native perennial plant Antirrhinum majus was scrutinized in this study for its antioxidant activity and its total phenolic content in order to test for the plant’s wound-healing capability. The traditional uses of this plant to treat gum scurvy, various tumors, ulcers, and hemorrhoids were the main idea behind this study. Leaves and flowers of the A. majus were extracted by maceration. Pilot qualitative phytochemical tests were made to check the presence of various secondary metabolites. Quantitatively, the flowers’ macerate indicated superlative results regarding antioxidant activity and total phenolic content. However, the in vivo wound-healing capability study was made using 30 Wistar strain albino rats. This innovative part of the study revealed that the healing power of the flowers’ extract ointment (5% w/w) was superior compared to the leaves’ extract (5% w/w) and the positive-control ointments (MEBO) (1.5% w/w) (p ≤ 0.001). This activity was assessed by visual examination, wound-length measurement, and estimation of hydroxyproline content. Antirrhinum majus is a promising plant to be considered for wound healing. However, further testing (including histological examination and high-performance liquid chromatography (HPLC) analysis) is necessary to understand more about its mechanisms of action.

Diabetes Mellitus, the metabolic syndrome where the body either fails to produce or effectively utilize insulin, is associated with chronic morbidity. While a definitive cure for the disease is lacking, with the modern medicine offering mainly the means to control the extent of the disease, Complementary and Alternative Medicine (CAMs) offers additional/alternate means to tackle the disease. On the other hand, the lack of evidenced medical practices is a lacuna in most of the traditional medical applications. Clerodendrum infortunatum.L (Lamiaceae family), a perennial shrub found in the tropics, has been known for its numerous pharmacological properties and is found as a constituent in many Ayurvedic and Siddha drugs, especially for skin and respiratory ailments. The plant has a noted potential as anti-hyperglycemic and has been found to be used in traditional medicine for the treatment of diabetes. However, evidence based evaluations have not been conducted on the anti-hyperglycemic effect of the plant, especially with respect to the general mode of intake, i.e, the aqueous form. In the current study, the aqueous extract of C. infortunatum (CI), was scientifically assessed for its effect on streptozotocin induced diabetes in Wistar albino rats. The diabetic rats were divided into 5 groups of 6 animals each. For testing the efficacy of extracts, two groups were intra-orally provided with dosages of 200 mg/Kg and 400 mg/Kg of body weight of animals, respectively, of aqueous extracts of CI. Control groups were maintained for evaluation, which included vehicle control as well as with Glibenclamide, a standard anti-diabetic drug. The extracts at a dose of 400 mg/Kg body weight was found to be associated with significant amelioration of many of the diabetes induced conditions, suggesting that the plant extract could be a strong potential CAM candidate for therapeutic management of diabetes.

In recent years, oxidative stress and free radicals have been implicated in impaired wound healing.Ocimum sanctum(O. sanctum), a plant widely used in Ayurveda, possesses anti-inflammatory and antioxidant properties. The present study was undertaken to assess the potential of alcoholic and aqueous extracts in wound healing in Wistar albino rats. The rats were divided into five groups of six animals each. Group 1 is normal wounded control and the other four groups were treated with two different doses each of alcoholic and aqueous extract ofO. sanctum. The wound healing parameters were evaluated by using incision, excision and dead space wounds in extract-treated rats and controls. Both the doses of alcoholic and aqueous extract significantly increased wound breaking strength, hydroxyproline, hexuronic acid, hexosamines, superoxide dismutase, catalase, reduced glutathione and significantly decreased percentage of wound contraction and lipid peroxidation when compared with the control group. The results suggest thatO. sanctumhas antioxidant properties, which may be responsible and favorable for faster wound healing and this plant extract may be useful in the management of abnormal healing and hypertropic scars.
