This study examined the stainability and functionality of cotton dyed with the extract of Salvia Plebia R. Br. as a research preceding the development of health functional materials and fashion products with a healing motif. The CIELAB measurements of the cotton fabric dyed with the extract of Salvia Plebia R. Br. showed 73.32 for $L^*$, 1.7 for $a^*$, and 37.78 for $b^*$, while the Munsell measurements exhibited 2.63Y in color, 7.18 of brightness, and 5.49 of chroma. The degree of staining resulting from color fastness to laundering, and that resulting from color fastness to perspiration (acid and alkaline), as well as the level of color fastness to crocking (wet and dry) all stayed between relatively higher levels of 4 and 5. The fabric dyed also exhibited SPF 50+, an outstanding sun blocking performance. The deodorization rate was also excellent, rising from 97% to over 99% when the time elapsed increased from 30 minutes to 120 minutes. The fabric dyed also showed a 99.6% antimicrobial activity against staphylococcus aureus ATCC 6538, and a 71.4% antimicrobial activity against Klebsiella pneumoniae ATCC 4352. The aforementioned findings indicate that fabrics dyed with the extract of Salvia Plebia R. Br. contain the potential to be developed for use as health-related materials and fashion products that promote healing.

The purpose of the present study was to investigate the effect of Salvia Plebia R. Br. (SP) powder on the antioxidative defense system and oxidative stress in rats which were fed a high fat high cholesterol diet. Accordingly, the rats were divided into four experimental groups which were composed of a high fat high cholesterol diet group (HF), HF diet with 5% SP powder supplemented group (PA), a HF diet with 10% SP powder supplemented group (PB), and a normal group (N). Consequently, the hepatic catalase activity of the HF group was decreased compared to the normal group (N), but it is recorded that of the PA and PB groups were significantly increased. With this in mind, the PA and PB groups resulted in the case of significantly increased activities of hepatic GSH-px and SOD. The hepatic superoxide radical and hydrogen peroxide contents of the PA and PB groups were significantly decreased, as compared to the HF group. The GOT and GPT activities of the PB group were also significantly decreased when thus compared to the HF group. Notably, the carbonyl values contents of the PA and PB groups were significantly reduced compared to the HF group. The hepatic TBARS values in the liver were significantly reduced as measured in the PA and PB groups. These results suggest that the SP powder may reduce the incidence of oxidative damage, by the activation of an antioxidative enzyme in rats fed with high fat high cholesterol diets.
