Cooked Aconite Slices
- Chinese
- 熟附片
- Pinyin
- Shou Fu Pian
- Latin
- Aconiti Lateralis Radix Praeparata
Known in TCM as Shou Fu Pian (熟附片), this acrid and sweet, hot herb enters the Heart, Kidney, and Spleen. Traditionally, it restores collapsed Yang and rescues cold collapse - Shou Fu Pian is a cooked slice form of prepared aconite used for cold extremities, weak pulse, and severe Yang depletion, most often applied for kidney yang deficiency, low back pain, and joint pain. Modern research has identified Aconitine, among its active constituents.

TCM Properties

- acrid, sweet
- Temperature
- hot
- Channels
- Heart, Kidney, Spleen
Traditional Use
Primary Actions
- Restores collapsed Yang and rescues cold collapse - Shou Fu Pian is a cooked slice form of prepared aconite used for cold extremities, weak pulse, and severe Yang depletion.
- Warms Heart, Spleen, and Kidney Yang - it treats edema, diarrhea, abdominal cold pain, impotence, fatigue, and chronically weak circulation when deficient cold is dominant.
- Warms the channels and relieves cold-damp pain - the sliced form is commonly dispensed for cold Bi, joint pain, cold low-back pain, and limb pain that clearly improves with warmth.
- Assists Mingmen fire and lower-burner function - it supports formulas for urinary cold, weak knees, cold womb, and other chronic Yang-deficiency patterns.
Secondary Actions
- Shou Fu Pian is the cooked sliced form of prepared lateral aconite root and is easier to measure and decoct than block products while preserving the same overall warming direction.
- It is still typically pre-decocted and almost always combined with balancing herbs such as ginger, licorice, Bai Zhu, Fu Ling, or warming Kidney medicinals.
Classic Formulas
- Si Ni Tang - archetypal rescue formula for Shaoyin collapse and icy extremities.
- Zhen Wu Tang - warming formula for edema, dizziness, abdominal pain, and Spleen-Kidney Yang deficiency with retained fluids.
- Gui Zhi Fu Zi Tang - wind-cold-damp painful-obstruction formula in which aconite slices warm the channels and reduce fixed joint pain.
- You Gui Wan - warms Kidney Yang and gate-of-vitality fire for chronic cold debility, weakness, and infertility patterns.
Classical References
- Cooked sliced aconite remains part of the broader Fu Zi category described in classical and modern materia medica as hot, toxic, and indispensable for restoring Yang and dispersing severe cold.
- Daodi processing literature distinguishes cooked slices from black, white, salted, and other commercial slice forms, emphasizing the clinical importance of paozhi rather than any change in botanical identity.
- Traditional formula practice uses cooked aconite slices inside structured formulas and not as a free-standing tonic because their therapeutic power is inseparable from toxicity management.
Modern Research
Active Compounds
- Aconitine, mesaconitine, and hypaconitine - the main toxic diester alkaloids reduced by proper processing
- Benzoylaconine, benzoylmesaconine, and benzoylhypaconine - less toxic monoester products created by hydrolysis during processing and decoction
- Aminoalcohol-diterpenoid alkaloids - processed aconite constituents studied for cardioprotective effects
- C19-diterpenoid alkaloid arabinosides - aqueous-extract compounds with analgesic activity
- Fuzi polysaccharides and glucans - non-alkaloid fractions investigated for immune effects
Studied Effects
- A 2023 review found that processing is the main reason Fuzi can be used clinically at all, because it shifts toxic chemistry while retaining cardiovascular, anti-inflammatory, and immunoregulatory activity (PMID 36257343).
- Several aqueous-extract arabinoside alkaloids from Aconitum carmichaelii showed strong analgesic activity in a mouse writhing model, helping explain why cooked aconite slices remain important in cold painful-obstruction formulas (PMID 29881680).
- Aminoalcohol-diterpenoid alkaloids from Aconitum carmichaelii protected H9c2 cardiomyocytes against doxorubicin injury, supporting continued interest in processed aconite chemistry for heart-related indications (PMID 33387644).

Safety & Interactions
Contraindications
- Pregnancy
- Heat patterns, Yin deficiency with heat, or clear internal heat without cold
- Raw or inadequately processed aconite for internal use
- Unsupervised use in children, frail patients, or patients with significant arrhythmia risk
Cautions
- Shou Fu Pian is cooked but still toxic; it needs authenticated sourcing, careful dosing, and pre-decoction rather than casual self-use.
- Toxicity can begin with oral numbness, tingling, nausea, vomiting, diarrhea, weakness, and hypotension before progressing to dangerous arrhythmias.
- Traditional incompatibility cautions remain for Ban Xia, the Gua Lou group, Tian Hua Fen, Bai Ji, Bai Lian, and the Bei Mu group.
- 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
