Dihydromyricetin (DHM, also known as Ampelopsin, CAS No. 27200-12-0) has evolved from a traditional botanical flavonoid into a cornerstone functional ingredient for modern hepatoprotective, alcohol-recovery, and metabolic health formulations. Primarily extracted from the tender stems and leaves of Ampelopsis grossedentata (commonly known as Vine Tea or Teng Cha in Traditional Chinese Medicine), high-purity Dihydromyricetin 98% acts as a potent regulator of hepatic enzyme pathways and central nervous system receptor plasticity.
