In Traditional Chinese Medicine (TCM), prepared sichuan aconite are plants that belong to the 'Herbs that dispel Wind and Dampness' category. These herbs typically help treat what's called 'bi pain' (i.e. painful obstruction) in TCM. This roughly corresponds to arthritic and rheumatic conditions with pain, stiffness and numbness of the bones, joints and muscles.
Furthermore prepared sichuan aconite are plants that are Hot in nature. This means that prepared sichuan aconite typically help people who have too much "Cold" in their body. Balance between Yin and Yang is a key health concept in TCM. Those who have too much 'Cold' in their body are said to either have a Yin Excess(because Yin is Cold in nature) or a Yang Deficiency (Yang is Hot in Nature). Depending on your condition prepared sichuan aconite can help restore a harmonious balance between Yin and Yang.
Prepared Sichuan aconite also taste Bitter and Pungent. The so-called 'Five Phases' theory in Chinese Medicine states that the taste of TCM ingredients is a key determinant of their action in the body. Bitter ingredients like prepared sichuan aconite tend to have a cleansing action on the body by clearing Heat, drying Dampness and promoting elimination via urination or bowel movements. On the other hand Pungent ingredients tend to promote the circulations of Qi and Body Fluids. That's why for instance someone tends to sweat a lot when they eat spicy/pungent food.
The tastes of ingredients in TCM also determine what Organs and Meridians they target. As such prepared sichuan aconite are thought to target the Spleen, the Heart, the Kidney and the Liver. In TCM the Spleen assists with digestion, Blood coagulation and Fluids metabolism in the body. In addition to regulating Blood flow, the Heart is believed to be the store of the 'Mind' which basically refers to someone's vitality. The Kidneys do not only regulate the urinary system but also play a key role in the reproductive system and the growth and aging process of the body. The Liver is often referred as the body's "general" because it is in charge of regulating the movements of Qi and the Body Fluids. It also takes a leading role in balancing our emotions.
