PMFs, particularly nobiletin and tangeritin, are effective against lifestyle diseases such as diabetes and high blood pressure. Moreover, PMFs also act to whiten the skin and to suppress the production of matrix metalloproteinases and UV-induced inflammation factor. - Use of raw materials from a clearly identifiable production region
SHEKWASHA EXTRACT BG is made using only shekwasha produced in Okinawa. Fresh shekwasha grown on expansive contracted farms are used as raw materials and processed into this product. - Can be used as an additive in quasi-drugs
