Key symptoms associated with Dioscorea are neuralgic and colicky pains, primarily affecting the gastrointestinal system. The pains are typically severe, cutting, cramping, and grinding, and radiate out in all directions from a central point that may shift location. They may affect the area of the liver, radiating upward to the right nipple. In women, the pains may occur during menstruation. In men, Dioscorea is typically prescribed to treat renal colic associated with kidney stones, sharp pains radiating down the testicles and legs, and cold, clammy perspiration.
