Sarsaparilla if symptomatic and follow the doctor’s instructions to take this drug will not usually cause stomach pain, if used blindly may cause adverse reactions. Sarsaparilla is flat, sweet and astringent in nature, and is mainly used in liver meridian and kidney meridian. It has the efficacy of detoxifying and dispersing blood stasis, dispelling wind and removing paralysis (removing wind evils and eliminating paralysis), and inducing dampness and removing turbidness (using oozing dampness to expel dampness and evils from the urinary tract), and is suitable for the treatment of excessive discharge of blood, rheumatic paralysis, and drenching of the urination and other illnesses. Clinically, Sarsaparilla and aralia are often paired together to treat celiac disease, and this drug can also be used alone to treat numbness of the tendons and bones. Since there is no authoritative data confirming that sarsaparilla can cause stomach pain, it is usually assumed that eating sarsaparilla will not cause stomach pain. However, if you need to use the medicine, you must be instructed by a professional Chinese medicine practitioner.
