Mechanism of Action & Pharmacology:

  • Alkaloids (harmoline) have muscle relaxant and sedative effects.
  • Flavonoids are antispasmodic, anti-inflammatory and sedative.
  • Chrysin may be responsible for anxiolytic effects mediated via modulation of the GABA system including affinity to GABA receptors, and effects on GABA re-uptake. In vitro effects of an extract showed modulation of the GABA system including affinity to GABA(A) and GABA(B) receptors.
  • Anti-hypertensive effects of extract may be due to the GABA-induced antihypertensive effect and partially to the vasodilatory effect of polyphenols including luteolin.
