Notes

  • It treats Phlegm-Heat in the Lung and Damp-Heat in the Bladder equally effectively.
  • It is particularly effective for hematuria, scanty urination, and dangerously spiking fevers.
  • Lu Gen and Rz. Imperatae Bai Mao Gen both clear Heat, generate fluids, and promote urination. Lu Gen centers on the Lungs and Stomach and is especially effective at clearing Qi-level Heat — it cools the Lungs, drains the Stomach, guides out Phlegm-Heat, and vents and disseminates external pathogens, treating cough from Lung Heat in externally contracted disorders and failure of measles to erupt fully. Bai Mao Gen, by contrast, is better suited to clearing Blood-level Heat and cooling the Blood to stop bleeding; it centers on the Heart, Lungs, Stomach, and Bladder, guiding Heart Fire out through the urine, and treats epistaxis, hemoptysis, hematuria, and jaundice from Damp-Heat. The two herbs are closely related and may substitute for each other when needed.
  • Fresh Reed Rhizome Xian Lu Gen is cool, sweet, and very juicy, and more potent than the dried root at cooling Heat and generating fluids. It is used whenever Heat from a warm pathogen disease produces Wei-level or Qi-level disorders, or for residual pathogenic influence left over from a febrile illness, as long as thirst from Yin injury is present; the dosage should be increased three- to five-fold.
  • Succus Phragmitis Rhizomatis (Fresh Reed Rhizome Juice) Xian Lu Gen Zhi strongly nourishes Yin and restores fluids, and suits febrile disorders with restless thirst and Stomach Heat with nausea and vomiting, in cases where decoctions cannot be tolerated.
  • Reed Stalk Wei Jing enters the Heart and Lungs to treat Deficiency Heat in the upper Jiao.
