How It Works
The formula's primary compounds patchoulol from Pogostemon cablin and perillaldehyde from Perilla frutescens modulate the enteric nervous system and enhance gastric motility. These bioactives interact with 5-HT3 and muscarinic receptors to regulate digestive function while volatile oils stimulate immune cell activity. The synergistic herb combination balances the autonomic nervous system through hypothalamic-pituitary-adrenal axis modulation.
