potassium nitrate + strontium chloride + paeonol

This is a combination of three active ingredients—potassium nitrate, strontium chloride, and paeonol—primarily formulated as a toothpaste for the management of dentine hypersensitivity (DH). Potassium nitrate acts by depolarizing nerve endings in the dental pulp to reduce pain transmission. Strontium chloride works by occluding dentinal tubules, thereby blocking external stimuli from reaching nerves. Paeonol is a natural compound with anti-inflammatory and analgesic properties, derived from the root bark of Paeonia suffruticosa. Clinical trials have demonstrated that this combination significantly reduces symptoms of dentine hypersensitivity compared to placebo toothpaste[1][2][3]. The product is considered a novel functional ingredient blend for anti-hypersensitivity oral care.
