Di Gu Pi

Di Gu Pi (Lycii Cortex): A Powerful Yin-Cooling Herb for Heat, Lung Support, and Deficiency Recovery

Introduction to Di Gu Pi (Lycii Cortex)

Di Gu Pi (地骨皮), the dried root bark of Lycium chinense or Lycium barbarum, is a time-honored herb in Traditional Chinese Medicine (TCM) known for its ability to clear deficient heat, cool the blood, and support lung and liver function. Unlike herbs that merely suppress symptoms, Di Gu Pi addresses internal imbalances associated with Yin deficiency—making it especially valuable for those experiencing night sweats, chronic low-grade fevers, and dry cough.

Di Gu Pi Health Benefits & Information

Therapeutic Indications

1. Yin Deficiency with Steaming Bone Syndrome

Di Gu Pi is a premier herb for conditions such as low-grade afternoon fever, five-center heat, and night sweats, often seen in chronic illness, menopausal transition, or overuse of warming tonics.

2. Chronic Lung Heat Cough

This herb is effective in clearing heat from the lungs, stopping dry or blood-streaked coughs, and aiding recovery from tuberculosis or lingering respiratory infections.

3. Excess Heat in the Blood

Used for hemoptysis, epistaxis, or skin disorders with heat signs. It works synergistically with blood-cooling herbs like Sheng Di Huang or Mu Dan Pi.

4. Kidney Fire from Deficiency

In TCM, when Kidney Yin is depleted, internal heat may rise. Di Gu Pi is often included in formulas to drain fire while preserving essence—ideal for chronic fatigue, wasting disorders, or latent heat patterns.


How Di Gu Pi Works: Pharmacological Insights

  • Anti-inflammatory: Demonstrates significant ability to reduce cytokine-driven inflammation.

  • Antipyretic: Helps lower fever, especially in cases where conventional medications may be too strong.

  • Hepatoprotective: Promotes liver detoxification and protects against oxidative damage.

  • Antioxidant: Contains flavonoids and alkaloids that combat free radical activity.

  • Immunomodulatory: May support immune balance in Yin-deficient conditions or post-viral recovery.
