To promote the application of sour-sweet herbs for nourishing Yin

such as Shaoyao Gancao decoction (SGD) in treating pediatric diseases

the author summarized typical medical records that use SGD and its modified receipts based on syndrome differentiation. Cases included pediatric intestinal spasm

Tourette syndrome

bronchial asthma

and children night crying. The results showed that although the symptoms of children with Tourette Syndrome were different from those with night crying

the pathogenesis of both diseases showed common features. These features are 'Yang in the liver is often in excess' and 'Yang is frequently in excess while Yin is often in deficiency'. SGD contains sour-sweet herbs which can nourish Yin

and harmonize liver and spleen. It functions in a way to nourish blood and Yin

suppress hyperactive liver and wood

astringe and soften liver. The use of SGD targeted the pathogenesis of both diseases and therefore achieved a satisfactory effect. The use of SGD for pediatric intestinal spasm

and be used at the time when wheeze is widely presented in the lung in children with bronchial asthma

is based on syndrome differentiation as well as modern pharmacological research findings about SGD's antispasmodic

analgesic

anti-inflammatory

cough-relieving

and anti-allergic effects. This suggests prescriptions selected based on traditional Chinese medicine theories and modern pharmacology research findings can serve multiple purposes and improve clinical outcomes.
