What is the difference between aconite and epiphyllum tianxiong?

The difference between aconite and epiphyllum tianxiong is mainly due to the inconsistency of the parts of the plant aconite used in the three.
The aconite is made from the tuberous roots of the plant aconite or the northern aconite, which has the efficacy of dispelling wind and dispersing cold, removing dampness and relieving pain, and is mainly used for treating paraplegia (one side of the limbs can not be moved freely), contractures of the hands and feet, osteoarthritis, bruises and swelling pains, and cold pains in the stomach and abdomen, and other diseases.
Pseudostemma is a traditional Chinese medicine made from the lateral root of aconite (root) of the buttercup plant, with the effect of returning yang to save reversal (by warming yang to save fainting, unconsciousness, etc.), dispersing cold and removing dampness, treating yin-shengge yang, edema of the feet, wind-cold-dampness paralysis, cold pains in the heart and abdomen, and cold dysentery.
Tianxiong is made from the caudex (without lateral roots) of aconite, family Buttercupaceae, with the efficacy of dispelling wind and dispersing cold, benefiting fire and helping yang, and is used for treating wind pain in the joints, contracture of limbs, paralysis of wind-cold and dampness, cold pain in the heart and abdomen, and obstruction in the abdomen. It should be contraindicated in cases of yin and yang deficiency and in pregnant women.
The above three herbs are all from aconite, but the choice of aconite made of different parts and made of different herbs, the specific use of medication should be carried out under the guidance of specialists, not unauthorized use of medicines.
