Uwagi

  • Its most common use is for Damp-Heat in the Lower Jiao.
  • It resembles Rz. Coptidis Huang Lian, Rx. Scutellariae Huang Qin, and Cx. Phellodendri Huang Bai, though it targets the Lower Jiao specifically.
  • Its bitterness is so pronounced that many cannot tolerate it as a tea, making pill or extract forms preferable.
  • It suits Milky Lin.
  • In small doses (under 1g) it stimulates the Stomach, raising gastric acid output and aiding digestion, but at high doses it irritates the Stomach, producing nausea, vomiting and loss of appetite.
  • It is reputed to treat unbearably painful limbs.
  • Research has shown it inhibits cancer cell growth.
  • It has been called a “sound herb for Stomach diseases.”
  • It is said to resolve hematochezia caused by alcohol poisoning.
  • It is said to increase bile flow.
  • It also guards the Liver against chemical damage.
  • It reduces blood pressure.
  • It is reputed to be four to seven times as potent as aspirin.
  • Long Dan Cao and Cx. Phellodendri Huang Bai both clear Damp-Heat from the Lower Jiao, but Long Dan Cao excels at draining Excess Liver/Gallbladder Fire while Huang Bai mainly drains Deficiency ministerial Fire.
  • Long Dan Cao and Rx. Gentianae Macrophyllae Qin Jiao both eliminate Dampness and reduce Heat, and both treat Damp-Heat jaundice. Qin Jiao expels Wind-Dampness without excessive drying and is used mainly for Wind-Damp Bi and Steaming Bone disorder with tidal fever, while Long Dan Cao, bitter and very cold, chiefly drains Fire from the Liver channel and Lower Jiao Damp-Heat, addressing Liver Fire with red eyes, vertigo and tinnitus, cramp and spasm from Liver Heat generating Wind, and vaginal swelling and itching from Lower Jiao Damp-Heat.
  • Raw Gentian, Sheng Long Dan, mixed with water is often used externally as eye drops for swollen, red, painful eyes.
  • Scorched Gentian, Jiao Long Dan, enters the Blood level to cool Blood and stop bleeding; it is milder and less injurious to the Spleen and Stomach, less drying, and gentler on Yin and Blood. It is often chosen for hemafecia or hematuria from alcohol poisoning or Intestinal Wind.
  • Wine-fried Gentian, Jiu Chao Long Dan Cao, moves upward to clear toxic Fire from the head and face, commonly used for swollen, red, painful eyes, tinnitus and a bitter taste; it is less cold and less prone to causing obstruction, and is most effective for rib pain from Liver/Gallbladder Fire.
