Embodiment 1
[0040] Example 1 Extract stimulation response experiment
[0041] The present invention screened out these three kinds of extracts from dozens of extracts through scientific screening, and the stimulation response degree of the three kinds of extracts was tested as follows:
[0042] Stimulation positive substance: 0.1 wt% SLS aqueous solution, ie, an aqueous solution formed by 99.9 g of water and 0.1 g of sodium lauryl sulfate (Sodium Lauryl Sulfate, SLS), was used as a stimulus model positive substance.
[0043] Test substance: 0.1wt% SLS aqueous solution was added with different concentrations of plant extracts as test substance.
[0044] Experimental method: Place the stimulus-positive substance and the substance to be tested in the patch chamber respectively, apply it to the subject's back, and uncover it after 24 hours, and observe the skin irritation response for 0.5h, 24h and 48h. The sample size was 35 people.
[0045] Result statistics: The number of cases with stim...
