Traditional Use
Primary Actions
- Restores devastated Yang and rescues collapse - Fu Pian is a prepared aconite slice used when cold collapse presents with cold limbs, a faint pulse, somnolence, or severe Yang exhaustion and a rapid warming response is needed.
- Warms Heart, Spleen, and Kidney Yang - it treats deep cold with weak circulation, edema, watery diarrhea, abdominal cold pain, fatigue, and failure of transformation in deficient-cold patterns.
- Warms the channels and disperses cold-damp pain - the slice form is widely used for cold Bi, fixed joint pain, and cold low-back or knee pain that improves with heat.
- Assists fire and supports Mingmen function - it is added to formulas for impotence, cold womb, frequent urination, or chronic lower-body weakness when Yang deficiency predominates.
Secondary Actions
- Fu Pian usually refers to processed decoction slices such as black slices or white slices that have undergone paozhi to reduce diester-alkaloid toxicity before dispensing.
- Even as a processed slice, it is commonly pre-decocted before the rest of the formula because warming power is desired only after toxicity has been reduced as much as possible.
Classic Formulas
- Si Ni Tang - classic rescue formula pairing Fu Zi-type aconite with Gan Jiang and Zhi Gan Cao for Shaoyin collapse, icy extremities, and a faint pulse.
- Zhen Wu Tang - warms Spleen and Kidney Yang while mobilizing water for edema, dizziness, abdominal pain, and deep deficient cold.
- Gui Zhi Fu Zi Tang - channel-warming formula for wind-cold-damp painful obstruction with deep cold and joint pain.
- Fu Zi Tang - deficiency-cold painful-obstruction formula for chronic joint pain, heaviness, and weakness with internal cold and Qi-Blood insufficiency.
Classical References
- Chinese Pharmacopoeia descriptions of prepared aconite slices emphasize strong heat, toxicity, and use for reversal of devastated Yang, warming fire, and dispersing cold pain rather than casual tonic use.
- Classical Shang Han Lun and Jin Gui traditions consistently decoct Fu Zi-type preparations first and pair them with stabilizing herbs such as Gan Jiang, Gan Cao, Bai Zhu, or Fu Ling according to the pattern being treated.
- Paozhi traditions distinguish commercial slice forms such as Hei Shun Pian and Bai Fu Pian, reflecting the longstanding need to process the lateral root before clinical use.
Modern Research
Active Compounds
- Aconitine, mesaconitine, and hypaconitine (diester-diterpenoid alkaloids) - the primary toxic alkaloids of raw aconite
- Benzoylaconine, benzoylmesaconine, and benzoylhypaconine (monoester alkaloids) - less toxic hydrolysis products enriched by processing and decoction
- Aminoalcohol-diterpenoid alkaloids - cardioprotective constituents isolated from processed lateral roots
- Fuzi polysaccharides and glucans - non-alkaloid fractions with emerging immunomodulatory interest
- Glycosidic diterpenoid alkaloids such as aconicarmichosides - unusual aqueous-extract compounds studied for analgesic activity
Studied Effects
- A 2023 review of Fuzi literature found more than 100 compounds and concluded that processing materially changes toxicity, chemistry, and pharmacology while preserving cardiovascular, anti-inflammatory, and immunomodulatory potential (PMID 36257343).
- Aminoalcohol-diterpenoid alkaloids isolated from Aconitum carmichaelii showed cardioprotective effects against doxorubicin-induced H9c2 injury, supporting the traditional Heart-Yang indication of prepared aconite products (PMID 33387644).
- Ginger enhanced the anti-heart-failure effect of Aconiti Lateralis Radix Praeparata in an acute heart-failure rat model, with improvement in heart function and mitochondrial energy-metabolism markers compared with Fuzi alone (PMID 28987949).

Safety & Interactions
Contraindications
- Pregnancy
- Heat syndromes, Yin deficiency with heat, or true fluid depletion without cold
- Raw, under-processed, or under-decocted aconite for internal use
- Known ventricular arrhythmia or unstable severe cardiac disease without expert supervision
Cautions
- Fu Pian remains toxic even after processing; it should be sourced as an authenticated prepared product and typically pre-decocted 30-60 minutes or according to product instructions before the rest of the formula is added.
- Early aconite poisoning can present with lip or tongue numbness, tingling, nausea, vomiting, diarrhea, weakness, hypotension, and dangerous ventricular arrhythmias; suspected toxicity requires emergency care.
- Traditional incompatibility cautions remain for Ban Xia, Gua Lou and its seed or peel, Tian Hua Fen, Bai Ji, Bai Lian, and the various Bei Mu species.
- MSK page not found - drug interaction data not available from Memorial Sloan Kettering integrative medicine database
Drug Interactions
- Cardiac glycosides such as digoxin - additive arrhythmogenic risk
- Class I and III antiarrhythmic drugs - unpredictable electrophysiologic interaction
- Beta-blockers or other rate-slowing agents - may worsen bradycardia or mask early toxicity
- QT-prolonging medications - additive risk of malignant ventricular arrhythmia
