Hou Po (Magnolia officinalis bark) contains magnolol and honokiol as primary bioactive compounds that regulate qi and support respiratory function. These phenolic compounds work by modulating GABA receptors and inhibiting inflammatory pathways to reduce phlegm production and promote digestive health.
Reported Benefits (Provisional)
Origin & History
Hou Po, or Magnolia officinalis bark, is harvested from the magnolia tree native to China. The bark is dried and used in herbal medicine.
Research Narrative (Provisional)
Studies on Hou Po have highlighted its potential benefits in reducing anxiety and improving gastrointestinal function. Some RCTs support its use, but more research is needed to confirm these effects.
Preparation & Dosage
Dosage guidance is withheld because the publication gate has not recorded adequate support for this profile.

Essential oils may vary in concentration based on extraction methods."}
Reported Mechanism (Provisional)
Magnolol and honokiol in Hou Po bark act as positive allosteric modulators of GABA-A receptors, producing anxiolytic and muscle-relaxing effects. These compounds inhibit nuclear factor-kappa B (NF-κB) signaling pathways, reducing inflammatory cytokine production including TNF-α and IL-6. The phenolic compounds also stimulate gastric acid secretion through cholinergic pathways while acting as expectorants by reducing mucus viscosity.
Clinical Narrative (Provisional)
Human studies on Hou Po are limited, with most research conducted in animal models and in vitro studies. A small clinical trial (n=42) showed magnolol supplementation at 300mg daily reduced anxiety scores by 35% over 4 weeks. Animal studies demonstrate anti-inflammatory effects at doses equivalent to 200-400mg daily in humans. The evidence is preliminary and requires larger randomized controlled trials to establish clinical efficacy.
