四逆汤 〔四逆湯〕sì nì tāng
Source: Shāng Hán Lùn 伤寒论
Ingredients:
- Fù zǐ (附子 Aconiti Radix Lateralis Praeparata, aconite [accessory root]) 10g
- Gān jiāng (干姜 Zingiberis Rhizoma, dried ginger) 10g
- Gān cǎo (甘草 Glycyrrhizae Radix, licorice [root]) (mix–fried) 12g
Action: Returns yáng and stems counterflow.
Indication:
Category: Interior-warming formulas / Yáng-returning desertion-stemming formulas
Method: Decoct with water.
Warnings: Contraindicated in
Rationale: Fù zǐ is very hot and very acrid agent that warms and supplements kidney yáng. Although it acts swiftly, its effect is not long-lasting. Hot acrid Gān jiāng warms and supplements spleen yáng. Its effect last longer than that of Fù zǐ, although it is slower acting. These two agents are therefore mutually complementary in their action. Zhì gān cǎo is sweet and warm. Combined with Fù zǐ, it resolves the latter's toxicity and warms and invigorates heart yáng. Combined with Gān jiāng, it softens the harshness of ginger. The formula as a whole provides yáng-returning and counterflow-stemming action that is both quick-acting and long-lasting without side effects.
