Seal Penis and Testes

Traditional Use

Primary Actions

• Warms Kidney Yang and supports sexual function ... Hai Gou Shen is a historical specialty tonic used for impotence, cold weakness of the lower burner, and diminished reproductive drive.
• Nourishes essence and supports marrow ... older trade literature extends its use to infertility, constitutional depletion, and weakness following prolonged deficiency.
• Strengthens the lumbar region and knees in deep deficiency-cold states ... it is used when reproductive weakness is accompanied by soreness, frailty, or coldness below the waist.

Secondary Actions

• Hai Gou Shen is a niche animal-derived medicinal and is now far less common in contemporary practice because legal, conservation, authentication, and ethical concerns dominate modern sourcing.
• Traditional Kidney-Yang tonic logic sometimes compares Hai Gou Shen with Lu Bian or Gou Shen, but these are not interchangeable source materials and should not be flattened into one record.

Classic Formulas

• Kidney-Yang tonic wine traditions with Lu Rong, Yin Yang Huo, and Rou Cong Rong ... used when impotence and infertility arise from deep lower-burner cold.
• Tonic pill combinations with Tu Si Zi, Ba Ji Tian, and Gou Qi Zi ... broader essence-and-yang support strategy for cold infertility and lumbar weakness.

Classical References

• TCM Wiki records Hai Gou Shen as salty and hot, entering the Liver and Kidney channels, with actions of warming the Kidney, tonifying Yang, and nourishing essence and marrow.
• Older trade literature treats it as a specialty tonic for impotence, lumbar weakness, and premature ejaculation rather than as a routine household decoction herb.
