Safety. This formula contains 罂粟壳, the dried husk of the opium poppy. It should be named for what it is: a material that contains morphine and codeine. It is in the formula precisely because opioids slow the gut, and that is also why it cannot be treated as an ordinary botanical. Opioid analgesics cause constipation, sedation and urinary retention, they produce dependence, and in children they can cause dangerous respiratory depression. Poppy material is a controlled substance in China and restricted in many other jurisdictions. That is why this formula is not something a reader should be preparing, importing or taking on their own initiative, and it is why 罂粟壳 in food and supplement products is a recurring enforcement problem. - The second problem is the symptom. Chronic diarrhoea being held with an astringent is diarrhoea whose cause has not been found. Blood in the stool, unintentional weight loss, diarrhoea that wakes a person from sleep, fever, or new diarrhoea following antibiotics all point to things that need investigation - inflammatory bowel disease, colorectal cancer, Clostridioides difficile infection, coeliac disease and bile acid diarrhoea among them. Nocturnal diarrhoea in particular is a marker of organic rather than functional disease. Suppressing the symptom with an opioid-containing astringent is a documented way people reach a diagnosis later and at a more advanced stage. - 木香 is a name with a real safety story attached. 青木香, a different article derived from Aristolochia species, was the cause of the aristolochic acid nephropathy and urothelial cancer cases that reshaped herbal regulation, and it is banned. Legitimate 木香 (Aucklandia / Saussurea costus) is not an Aristolochia, but commercial substitution among look-alike articles sold as 'mu xiang' is exactly how those cases arose. Saussurea costus is also listed in CITES Appendix I, so provenance matters. Sesquiterpene lactones make cross-reactivity plausible in Asteraceae (daisy, ragweed) allergy. - 肉桂 is cassia bark, the cinnamon chemotype whose coumarin content is hepatotoxic at sustained intake and which has anticoagulant properties. - 当归 carries case-report-level signals of potentiating warfarin. 甘草 (licorice) causes sodium retention, potassium loss and raised blood pressure, and therefore interacts with digoxin, potassium-losing diuretics, corticosteroids and antihypertensives. 人参 has a documented interaction with warfarin and can produce insomnia and blood pressure changes. - 肉豆蔻 is nutmeg, roasted here; myristicin-containing nutmeg is a well-described toxic presentation at high intake. - Not for self-administration. Amounts are set by a licensed practitioner and are deliberately not given here.
