This study investigated Liu-Wei-Dihuang and its components using pulse analysis. The formula and herbs modulate blood flow in different organ meridians based on resonance frequency, offering insights into traditional Chinese medicine mechanisms.

Area of Science:

  • Pharmacology
  • Traditional Chinese Medicine
  • Physiology

Background:

  • Traditional Chinese Formula (TCF) Liu-Wei-Dihuang is widely used.
  • Understanding the physiological mechanisms of TCFs and their components is crucial.
  • Resonance theory offers a novel framework for analyzing herb-meridian interactions.

Purpose of the Study:

  • To elucidate the mechanism and mutual reactions of Liu-Wei-Dihuang and its five main components.
  • To investigate the effects of these herbs on blood flow in different organ meridians based on resonance frequency.
  • To apply a recently developed resonance theory to analyze traditional Chinese medicine.

Main Methods:

  • Pulse analysis method was employed.
  • Hot water herbal extracts were administered intraperitoneally to rats.

  • Pressure pulse spectrum at the caudate artery was measured to assess blood flow dynamics.

    • Main Results:

    • Liu-Wei-Dihuang increased blood flow to low resonance frequency meridians (liver C1, kidney C2, spleen C3) and decreased it in high resonance frequency organs (lung C4, stomach C5, gall bladder C6, bladder C7), reducing heart load (C0).
    • All five components increased blood flow to kidney (C2) and spleen (C3).
    • Individual components exhibited varied effects on other organs: Alisma plantago-aquatica decreased C0, C5, C6, C7; Poria cocos decreased C1, C4, C5, C6; Rehmannia glutinosa and Paeonia Suffruticosa decreased C0, C4, C5, C6, C7; Cornus officinalis increased C4 but decreased C0, C5, C6, C7.

    Conclusions:

    • Liu-Wei-Dihuang and its components exert differential effects on blood flow across various organ meridians.
    • The observed effects align with traditional Chinese medicine principles and can be explained by the resonance theory.
    • This study provides a scientific basis for understanding the therapeutic actions of Liu-Wei-Dihuang in traditional Chinese medicine.
