Actions and Therapeutic Effects of Boric Acid Powder

Boric acid powder is primarily indicated for patients with skin allergies. Its main action is antimicrobial and disinfectant. These preparations are non-toxic when used appropriately and may be taken orally in moderate doses under medical guidance. However, boric acid preparations possess certain irritant properties; therefore, direct application to open wounds should be avoided, as this may cause irritation and delay wound healing. Patients should consult a physician before use to determine the appropriate dosage based on individual circumstances. Additionally, supplementation with vitamins may be recommended.

Boric acid powder is typically prepared as a 3% aqueous solution—i.e., 3 g of boric acid powder dissolved in warm water for immediate use. It appears as a white, odorless, non-irritating solid powder. Upon dissolution, it exhibits antiseptic and bactericidal activity and can be applied topically as a cold or moist compress. It is commonly used in the management of dermatitis, eczema, and other inflammatory skin conditions characterized by exudation and erosion during the acute phase.

Topical application of boric acid solution helps reduce exudation and exerts anti-inflammatory and infection-preventive effects. It may also be used to treat infantile eczema. Prolonged, large-area, or continuous topical use should be avoided, as systemic absorption may lead to toxicity. Once exudation and erosion have resolved, topical boric acid solution should be discontinued and replaced, if necessary, with topical anti-inflammatory agents. In daily life, patients should avoid spicy and irritating foods and instead consume bland, easily digestible meals. We hope this information is helpful to you!
