Effect of green tea (Camellia sinensis) extract on healing process of surgical wounds in rat

Green tea (Camellia sinensis) has anti-oxidant and anti-inflammatory properties and may enhance wound healing process. The present study, therefore, was aimed to examine the effect of green tea ethanolic extract on wound healing process. For this experimental study, 36 healthy male Wistar rats were randomly designated to three groups of A, B, and C which, respectively treated with, Vaseline þ 0.6% green tea extract, Vaseline and normal saline for 21 days. Wounds’ length and area were measured by caliper every other day and specimens were taken at 3rd, 12th, and 21st day for microscopical examinations. Data were analyzed by SPSS 16 using survival analysis (Breslow test), repeated measured ANOVA, one-way ANOVA and ManneWhitney. P < 0.05 was considered as statistically significant. The mean healing duration of surgical wounds in groups A and B was 14.66 and 20.66 (P ¼ 0.018), respectively. Decrease in healing duration in the group A was significantly higher within the first two weeks compared with control groups (P ¼ 0.05). Microscopic examinations also indicated a significant difference in wound healing process between groups A and C throughout the whole study duration as well as groups A and B during the 3rd week of the study (P < 0.05). Green tea extract could help wound healing process, probably effective on surgical wounds healin

Assessment of the effects of bean extract on axillary hair reduction

Objective: Body hair removal plays an important role in beauty standards, particularly for women. Finding a method that is easy to use, cheap, and can be done without supervision can significantly affect long-term hair reduction and reduce the side effects of hair removal. The present study investigated the impact of a containing 20% broad bean (Vicia faba) extract cream on axillary hair removal.Materials and Methods: Twenty-five female volunteers were randomly divided into A (right axillary intervention - left axillary placebo) and B (right axillary placebo - left axillary intervention). Depending on the group, each person used a cream containing 20% broad bean extract )"The extract made from the seeds and pods of broad beans.") on one side and a placebo on the other twice a day for three months. Volunteers shaved their axillary hairs three days before each visit and took pictures of both sides on the day of the visit with a trichoscope (to check the diameter and thickness of the hairs).Results: We found a decrease in thickness on the intervention group (the axilla where a cream containing broad bean extract was applied); however, this difference was not significant between the intervention side and the placebo. In terms of the number of hairs, the difference between the two groups was significant only in the second month despite the decrease on the intervention side. Evaluation based on the personal judgment of the volunteers showed that there was a substantial difference in terms of the number of hairs (p=0.012) and thinning of hair (p=0.02).Conclusion: Our findings showed that 20% broad bean extract cream could potentially reduce axillary hair growth
