Hai Gou Shen (Male Seal Sexual Organs)

Chinese Herb Actions

Chinese Herb Dosage

• What is the typical dosage of Hai Gou Shen?

  Traditional materia medica gives roughly 3–9 g, decocted, or soaked in wine. This range is reported consistently in the TCM reference literature for this substance; no additional preparation nuance (e.g., processing method) was found beyond decoction or wine-steeping.

  Source: multiple online sources. Reference only — not a prescription. Hai Gou Shen is a legally restricted, rarely available substance in current practice (see cautions).

Chinese Herb Contraindications & Cautions

• Are there cautions for Hai Gou Shen?

  As a hot, salty yang tonic, this category of herb is traditionally unsuited to yin-deficiency-with-heat or excess-fire patterns — the same categorical caution TCM references give for the closely related Gou Shen (dog penis/testes), which is explicitly listed as contraindicated in internal heat/excess fire. No Hai Gou Shen–specific contraindication beyond this general yang-tonic principle was found in the sources reviewed.

  • Legal/regulatory (reference note, not medical advice) — the source animals (Northern fur seal, Callorhinus ursinus; harbor seal, Phoca vitulina) are protected marine mammals. In the United States, the Marine Mammal Protection Act (16 U.S.C. §1361 et seq.) prohibits the take, possession, transport, and sale of marine mammals and their parts absent a permit, with knowing violations carrying fines up to $20,000 and/or up to one year imprisonment per violation (civil penalties up to $10,000 per violation). The Northern fur seal is also covered by the U.S. Fur Seal Act of 1966.
  • Conservation status (reference note) — the Northern fur seal is assessed Vulnerable on the IUCN Red List, and its Pribilof Islands/Eastern Pacific stock has been designated “depleted” under the Marine Mammal Protection Act since 1988 (population down more than 50% from roughly 2.2 million in the 1950s). The harbor seal is globally Least Concern, though some regional subspecies are in steep decline. Because of this status and legal restriction, Hai Gou Shen is essentially unavailable in legitimate contemporary practice; it is documented here as encyclopedia reference, not a sourcing recommendation.

Legal/conservation facts are neutral reference disclosures, not administration guidance.

Chinese Herb Toxicity & Overdose

• No dedicated toxicological data for Hai Gou Shen was found in the materia medica or biomedical literature searched. The substance is now effectively outside legitimate commercial circulation in most jurisdictions because of its protected-species/legal status (see cautions), which limits both its practical use and the research base available on it.

  General reviews of animal-derived TCM materials (not specific to Hai Gou Shen) flag category-level concerns relevant to any such product: zoonotic-disease transmission risk from processed animal tissue, and variable product quality/authenticity in the absence of regulated sourcing.

  Source: Still J, “Use of animal products in traditional Chinese medicine: environmental impact and health hazards,” Complement Ther Med 2003 (PMID 12801499) — general review, does not study Hai Gou Shen specifically. Reference note, not a safety guarantee.

Herb-Drug Interactions

• No documented herb–drug interaction data was found for Hai Gou Shen in the sources searched. This most likely reflects the absence of modern pharmacological study on the substance (see research) rather than a confirmed absence of interaction risk.

Western / Biomedical Research

Chinese Herb Clinical Studies & Research

Provided as research context — a summary of published biomedical study, not a therapeutic or medical claim.

• Is there modern research on Hai Gou Shen (Testes et Penis Otariae)?

  No, targeted PubMed/PMC searches found no pharmacological or clinical studies specific to Hai Gou Shen, its source seals, or their genital tissue. What is well documented instead is the conservation and legal status of its source animals.

  • No substance-specific pharmacology or clinical trials — searches for “Hai Gou Shen,” “seal penis,” Callorhinus ursinus, and Phoca vitulina in combination with TCM/pharmacology/andrology terms returned no dedicated studies of this material.
  • Animal-derived TCM materials, general review — a 2003 review discusses ecological, ethico-legal, and health concerns (zoonoses, product quality, endangered-species trade) for animal-tissue TCM preparations broadly, without studying Hai Gou Shen specifically.
  • Conservation status is the best-documented fact set — Northern fur seal assessed Vulnerable (IUCN); its Eastern Pacific/Pribilof stock designated “depleted” under the U.S. Marine Mammal Protection Act since 1988; harbor seal assessed Least Concern globally with some threatened regional subspecies (see cautions for full detail and sources).

  Note: this site’s own record currently records toxic/endangered flag = false for this herb, but its source species (fur seal, harbor seal) carry verified protected/Vulnerable conservation status and US federal legal restrictions (above). This looks like a data-quality gap rather than a real conflict in the source material; flagged for owner review rather than changed here.

Chinese Herb Notes

• How is Hai Gou Shen different from Gou Shen (dog penis)?

  Hai Gou Shen and Gou Shen are two distinct, similarly named animal-derived Kidney-yang tonics — easy to confuse in transliteration. Both are salty and hot, but they come from different animals, enter different channel sets, and carry different typical dosages.

  • Hai Gou Shen (“sea dog kidney/genitals”) — Testes et Penis Otariae, from seal (fur seal or harbor seal); enters Kidney and Liver; traditional dosage ~3–9 g.
  • Gou Shen (“dog kidney/genitals”) — Testes et Penis Canis, from dog; enters Kidney only; traditional dosage ~1.5–3 g; a reference source lists it as contraindicated in patterns of internal heat/excess fire, and combined with Gou Qi Zi, Ba Ji Tian, and Tu Si Zi for Kidney-yang deficiency with impotence, cold aversion, and cold extremities.

  No formulas in this site’s own record reference Hai Gou Shen.

This herb is from an endangered/protected species and is illegal in the United States
