Step 5 of 6: 少陽相火 (Shaoyang ministerial fire)
23 Sep – 22 Nov — 秋分 (Autumn Equinox) to 小雪 (Minor Snow).
The qi year is divided into six steps (六氣) of about 61 days each. Every step carries a fixed host qi (主氣) — the weather that season always has — under a guest qi (客氣) that moves round with the year. This one pairs guest 少陽相火 (Shaoyang ministerial fire) over host 陽明燥金 (Yangming dry-metal).
- Year movement (中運) — the year's governing phase
- 太羽 · water, in excess (太過)
- Celestial controller (司天) — the qi over the whole year
- 少陰君火 Shaoyin sovereign fire
- Earthly spring (在泉) — its partner, over the second half
- 陽明燥金 Yangming dry-metal

Reference first, tools second
The monographs are the product. The AI tools read from them — they don't replace them.
Materia medica
Herb monographs with pinyin and Latin names, taste, temperature and channels, functions, preparation, dosage ranges, constituents, and safety data.
Formulas & points
Classical formulas with source texts, jun/chen/zuo/shi roles, and gram weights — alongside acupuncture points and the patterns they treat.
AI tools on the database
Symptom-to-pattern analysis, herb–drug interaction and safety checks, and formula tools. The interaction, safety and formula tools run fixed safety rules and show the findings apart from the AI's answer. Educational, not a diagnosis.

Trust you can check
Sourced, not scraped
Official names, dosage ranges, and toxicity follow the Chinese Pharmacopoeia; formula compositions follow their classical texts; research links to peer-reviewed papers.
Empty beats wrong
A clinical field with no source stays blank. A wrong dose on a page a practitioner reads from is worse than none.
Safety checks that aren't AI
Classical incompatibilities (十八反 / 十九畏), pregnancy cautions, herb–drug rules, and dose ceilings (where amounts are entered) are fixed rules. The interaction, safety and formula tools run them on every result and show their findings apart from the model's, whatever it suggests.

Open a monograph, follow it to the formulas that use it, and check its safety profile against your medications.
