$RGC Over the years, Regencell’s CEO Yat-Gai Au witnessed significant improvement of a family friend’s son who had been diagnosed with attention deficit hyperactivity disorder (ADHD) and autism spectrum disorder (ASD). The child was treated by an extraordinary Chinese medicine practitioner and made noticeable improvements after just one month of treatment. Within two years of treatment, the child’s disorder had generally disappeared and was able to live a normal life. https://www.regencellbioscience.com/our-history/
