Condition analysis: Hello, Scutellaria baicalensis and Cortex Phellodendri are two different drugs in traditional Chinese medicine. Both Scutellaria baicalensis and Cortex Phellodendri have the effects of clearing away heat, detoxifying, drying dampness, and purging fire. However, Scutellaria baicalensis mainly clears the heat from the upper burnt lungs, liver, and stomach, while Phellodendron baicalensis mainly clears the heat from the lower burnt kidneys, small intestine, and bladder.

Opinions and suggestions: Generally, wind-heat colds are caused by upper-burning lung heat, and scutellaria baicalensis is more effective. For example, Qingkailing Capsules and Shuanghuanglian Oral Liquid both contain scutellaria baicalensis. Huangbai Capsule is mainly used to treat dysentery, jaundice, sores, vaginal discharge, hot stranguria, spermatorrhea, etc. caused by damp-heat in lower Jiao. It is not effective for colds.
