The article cites traditional Chinese medicine and the Compendium of Materia Medica, which historically associated fish maw with nourishing the kidneys, essence, muscles and tendons. These are traditional descriptions, not evidence that fish maw treats medical conditions.
Fish maw is a protein-rich dried seafood. The source repeats traditional claims about nourishing yin, the kidneys and general strength, but it should not be used to diagnose or treat back pain, weakness or any other condition.

1. Use with Chinese herbal formulas: The source lists peptic ulcers, tuberculosis, rheumatic heart disease, aplastic anaemia and vasculitis. These are serious conditions requiring qualified medical care; fish maw is not a proven treatment.

2. Fertility claims: The source links fish maw to seminal-vesicle fructose and names the formulas Yu Piao Sheng Jing, Bu Shen Sheng Jing Tang and Qu Zhuo Sheng Jing Tang. It also quotes an unreferenced 78% 'cure rate.' This is not reliable clinical evidence; infertility should be assessed by a qualified clinician.

3. Digestion: Traditional dietary accounts associate fish maw with the spleen, stomach and appetite. Evidence that it prevents or treats anorexia, indigestion, bloating or constipation is not established.

4. Physical strength: The source associates fish maw with muscle resilience, energy and reduced fatigue, but does not provide clinical evidence for these outcomes.

5. Skin claims: The article associates fish maw with smoother skin and less dryness or acne. These skincare effects are traditional or promotional claims, not proven results from eating fish maw.

6. Cognitive and developmental claims: The source says fish maw strengthens brain, nerve and internal functions, promotes growth and development, and improves thinking and intelligence. It claims that fish maw can prevent or treat intellectual decline, neurological slowing, slow reactions, poor childhood development, insufficient breast-milk production during pregnancy, and forgetfulness or insomnia in older people. It provides no clinical basis for these claims; developmental, neurological, cognitive, sleep or milk-supply concerns require qualified medical advice.

7. Immunity: The article combines fish maw's protein content with traditional claims about circulation, blood, cold and dampness. This does not establish that eating fish maw enhances immunity or stops bleeding.

8. Cancer claim: The source claims effects on oesophageal and stomach cancer and on lung perforation, but supplies no credible clinical evidence. Fish maw is not a cancer treatment and must not replace oncology or emergency care.

9. Cough claims: Some varieties are traditionally associated with easing coughs, but fish maw has not been established as a treatment or preventive measure for persistent cough.

10. Fatigue: Traditional dietary practice uses fish maw as a tonic for perceived weakness or yin deficiency. Persistent fatigue can have many causes and should not be self-treated with food alone.

11. Ovarian and hormonal claims: The source says fish maw accelerates ovarian-cell regeneration, restores endocrine balance and metabolism, returns ovarian function to its original state, and increases natural oestrogen secretion. It claims that ovarian follicles become full, fresh and active; oestrogen remains at a normal level; female endocrine function is regulated; blood flow to the endometrium increases and the endometrium gradually thickens; follicular function and menstruation return to normal; menopause is delayed by 5–10 years; and a younger-looking complexion is restored. These statements are unsupported and must not be presented as medical outcomes. Menstrual, fertility, endocrine or menopausal concerns require qualified clinical care.

12. Pregnancy claims: The source says a mother who eats fish maw will have a baby with very good immunity and skin and 'the whitest baby in the delivery room.' It recommends fish maw as the first choice for an anaemic mother seeking to replenish qi and blood, claiming that ordinary soup is not strong enough. It then says that, as the abdomen grows during pregnancy, sufficient collagen will reduce not only stretch marks but also wrinkles and crow's feet. These statements are unsupported; fish maw has not been shown to change a baby's immunity or complexion, treat anaemia, or prevent stretch marks or wrinkles. Pregnancy diet, supplements and anaemia require guidance from a qualified clinician.
