Tip of Licorice Root Classic Formulas … Natural Herb Library

Primary Actions

Clears heat and relieves painful urinary dribbling ... Gan Cao Shao is the narrow licorice-tip lane used in heat strangury patterns with burning, dribbling, or blood-streaked urine where the distal root tip is asked to guide fire downward.
Clears Heart fire that travels to the Small Intestine and Bladder ... it appears in formula logic for mouth sores, irritability, dark scanty urine, and heat being vented through urination rather than broadly tonified.
Moderates urgency and relieves pain while retaining licorice's harmonizing character ... compared with larger raw licorice-root lots, the tip presentation is less about general tonification and more about urinary and throat-facing use.

Dao Chi San ... the classic Heart-fire formula where Gan Cao Shao helps clear irritability and mouth sores by guiding heat out through the urine.
Ba Zheng San ... damp-heat strangury formula in which Gan Cao Shao supports painful urinary patterns alongside Qu Mai, Mu Tong, Hua Shi, and Che Qian Zi.
Heat-strangury and sore-throat modifications ... the tip form is often preferred when licorice is being used for fire, pain, and downward drainage rather than for heavy formula harmonizing.

Traditional herbology preserves Gan Cao Shao as the root-tip lane of licorice used especially for painful urinary disorders and Heart-fire patterns with mouth lesions.
The distinction between whole licorice root and licorice tip is a real dispensing instruction, not merely an importer naming artifact.
