zalf

Zalf is the Dutch term for an ointment or salve, a semi-solid preparation intended for topical application to the skin or mucous membranes. In Dutch pharmacology, zalf covers oil-based ointments as well as cream-like emulsions and pastes used for protective, medicinal, or cosmetic purposes. A zalf typically contains a vehicle that carries active ingredients, such as petrolatum, lanolin, waxes, or emulsified bases, along with stabilizers, preservatives, or fragrances.

Forms and ingredients vary, with ointments tending to be more occlusive and longer-lasting on the skin, creams providing lighter, quicker absorption, and pastes containing higher solid content for protective barriers. Active ingredients may include topical antibiotics, antifungals, corticosteroids, keratolytics, analgesics, or moisturizers, selected to treat infection, inflammation, dryness, itching, or wounds. The exact composition depends on the intended use, regulatory category, and local pharmaceutical practices.

Uses range from treatment of skin infections and inflammatory dermatoses to wound care, burns, fissures, eczema, and psoriasis. Zalf can also be used for cosmetic purposes, such as moisturizing or protecting dry skin. Veterinary applications exist as well, where zalf formulations are employed for animal skin care and therapy.

Manufacture and regulation vary by country. Zalf can be produced by pharmaceutical manufacturers or pharmacy compounding, and may be sold as over-the-counter products or require a prescription, depending on ingredients and claimed effects. Storage typically involves keeping the product in a cool, dry place and observing the labeled shelf life to ensure safety and effectiveness.

Etymology is linked to the broader family of words for salves and ointments in Germanic languages, reflecting its long-standing use as a topical preparation in medicine and care.
