Context Processing with vinegar could enhance the efficacy and reduce the toxicity of Curcuma phaeocaulis Valeton. (Zingiberaceae), a Chinese herbal medicine with anti-inflammatory and antitumor activities.Objective This study investigated the vinegar processing effects by evaluating anti-angiogenic effect and toxicity of C. phaeocaulis through zebrafish and rat models.Materials and methods Zebrafish embryos (AB and FLk-GFP strain) were applied to evaluate toxicity, cardiotoxicity and anti-angiogenic activity of volatile oil, and water decoction of the raw and vinegar-processed C. phaeocaulis. Meanwhile, a blood stasis syndrome rat model was applied to study the toxicity by measuring the ovarian and uterine coefficient.Results Curcuma phaeocaulis volatile oil and its vinegar-processed products in zebrafish had an LC50 of 67.315 and 95.755 μg/mL, respectively. Curcuma phaeocaulis water decoction and its vinegar-processed products had an LC50 of 161.440 and 206.239 μg/mL, respectively. The toxicity of vinegar-processed products was significantly lower than the raw, and the development characteristic of zebrafish embryos at different times confirmed these results. The volatile oil of vinegar-processed products could inhibit the growth of intersegmental blood vessels at the dose of 20 μg/mL, while the raw materials did not exhibit such effect at the same concentration. The rat experiment also confirmed that the volatile oil could reduce toxicity of ovarian and uterine.Discussion ...
