| As far as I know, mulberry contains no hydroquinone. Plants like bearberry and pipsissewa do contain a chemical called arbutin, which when taken internally, the body will convert to hydroquinone. How much depends on the body's relative alkalinity. Hydroquinone is a urinary antiseptic, and is commonly used for such infections. Taken in moderate doses for shorter periods, it is considered relatively safe. I know not what the effects of hydroquinone on the skin are; though I know of no plants that naturally contain other than its precursor arbutin. |
