Chinese medicine practitioners believe that cold calves are mostly related to spleen and kidney yang deficiency (deficiency of yang qi in the spleen and kidneys), which cannot warm the limbs, so medicines with the effect of warming and tonifying the yang qi of the spleen and kidneys, such as Lizhong Pills, can be chosen. Lizhong Pill is composed of Radix Codonopsis, Rhizoma Atractylodis Macrocephalae, Radix et Rhizoma Glycyrrhizae, Glycyrrhiza Uralensis, and Ginger, etc. It has the efficacy of warming the middle of the body, dispersing cold (dispersing the cold with medicines warming the spleen and stomach) and strengthening the stomach, and it can be clinically used in the treatment of spleen and stomach deficiency (spleen and stomach are weak and cold), vomiting and diarrhea, chest fullness (chest is distended and uncomfortable), abdominal pain, and indigestion. Caution should be taken when using it for people with cold and fever. For patients with cold calves, it is recommended to go to a regular hospital for consultation and treatment under the guidance of a medical doctor specializing in diagnosis and treatment.
