Safety. Su He Xiang Wan is recorded in the Taiping Huimin Hejiju Fang and it is the formula that gives the category warm-opening its content. Almost the entire prescription is aromatic, acrid and warm: storax, musk, borneol, benzoin, sandalwood, eagle wood, clove, long pepper, cyperus. The classical reading is that cold and congealed qi have closed the orifices, and that warmth and movement are what open them again.
The entry has to say, before anything about warming or aromatics, what the presentation actually obliges. Sudden collapse or sudden loss of consciousness is, in modern terms, an undifferentiated emergency until it is differentiated. Syncope, seizure, hypoglycaemia, stroke, intracranial haemorrhage, pulmonary embolism, aortic dissection, myocardial infarction, cardiac arrhythmia, sepsis, anaphylaxis, and poisoning all present as a person who has gone down or gone quiet. They are separated by examination, blood glucose, electrocardiography and imaging — not by whether the limbs are warm or the breath smells of something. The classical distinction between cool-opening and warm-opening is a distinction inside a tradition that had none of those tests; it is not a distinction a reader can make, and getting it backwards is not a neutral error, because a warm, circulation-stimulating preparation given to a person having a stroke is not the treatment a stroke needs.
Warmth also has a mechanical consequence here. A person who has collapsed may have an impaired gag reflex, and the aromatics in this formula are given as pills or powders, often historically dissolved and poured in. Anything poured into a mouth that is not protecting its airway goes to the lungs. Aspiration is mechanical. It does not negotiate.
On the ingredients: the classical list includes aristolochia root, genus Aristolochia, source of aristolochic acid — the cause of aristolochic acid nephropathy and urothelial carcinoma, and the reason these herbs are prohibited or restricted in many jurisdictions. Modern preparations generally use a costus-type wood instead; the library notes the original and does not endorse it. Cinnabar is mercuric sulfide, cumulative, with no established safe level for long-term use. Rhinoceros horn has been prohibited in China since 1993 and is routinely replaced by water buffalo horn; musk is from a CITES-listed animal and is often synthetic today. Benzoin is a recognised contact allergen; clove contains eugenol, which is hepatotoxic in overdose and is a known concern in young children; long pepper contains piperine, which inhibits several drug-metabolising enzymes and can raise the blood level of other medicines. Frankincense and myrrh-type resins are common causes of contact dermatitis.
This page is not a recommendation. No dose, no preparation, no regimen, no claim of benefit. Pregnancy, children, older adults, hepatic or renal impairment, epilepsy, cardiovascular disease, and any anticoagulant, antiplatelet, antihypertensive, antidiabetic or sedative medicine taken on medical advice each remove the remaining room. If a preparation like this has been taken and there is vomiting, abdominal pain, tremor, confusion, difficulty breathing, or reduced urine output, treat it as an emergency and bring the packaging.
苏合香丸著录于《太平惠民和剂局方》，是「温开」这一类得以成立的那一首方。全方几乎都是芳香辛温之品：苏合香、麝香、冰片、安息香、白檀香、沉香、丁香、荜茇、香附。古典的解释是寒与气凝闭阻清窍，以温与行开之。
在谈温与芳香之前，本条必须先说这个证候在今天意味着什么义务。突然昏倒或突然意识丧失，在现代是**未经分诊的急症**，直到被分诊为止：晕厥、癫痫、低血糖、卒中、颅内出血、肺栓塞、主动脉夹层、心肌梗死、心律失常、脓毒症、过敏性休克、中毒，都可以表现为一个人倒下去或静下去。区分它们靠查体、血糖、心电图与影像，而不是靠四肢是温是凉、口气是什么味。古典里「凉开」与「温开」之分，是在一个没有上述检查的传统内部作出的区分；读者无法据此判断，而判断反了不是中性的错误 —— 给一位卒中者投温通走窜之品，并不是卒中需要的处理。
「温」在这里还有一个机械后果。昏倒者的咽反射可能同时受损，而此方是丸散，历史上常被溶化后灌入。灌进一个不能保护自己气道的口腔，液体去的是肺。误吸是机械事件，它不谈判。
关于组成：原方所记**青木香**为马兜铃属植物，含马兜铃酸 —— 马兜铃酸肾病与尿路上皮癌的原因，也是多法域禁用或限制该类药材的理由；现代制剂多以木香类（云木香）代之，本库记原方之旧，不主张使用原方组成。朱砂是硫化汞，蓄积性毒物，没有确立的安全长期用量。犀角贸易自 1993 年起在中国被禁止，今多以水牛角代；麝香来自 CITES 所列物种，今多为人工麝香。安息香是已知的接触性过敏原；丁香含丁香酚，过量有肝毒性，对幼儿尤须谨慎；荜茇含胡椒碱，可抑制若干药物代谢酶，从而抬高同服药物的血药浓度；乳香一类树脂是接触性皮炎的常见原因。
本页不是建议：不列用量、不列制法、不列服法，也不主张它对任何情况有益。妊娠、儿童、老年、肝肾功能受损、癫痫、心血管疾病，以及正在使用抗凝／抗血小板／降压／降糖／镇静类处方药，任何一项都足以抹去残余的空间。若已服用此类制剂并出现呕吐、腹痛、震颤、意识改变、呼吸困难或尿少，属急症：立即就医，并把原包装带上。
