The hound’s tongue plant has been used from the 16th century onwards as part of some famous French pills (at that time) discovered by the renowned French surgeon Ambroise Pare (1510-1590). Beside hound’s tongue, these pills contained opium, henbane, saffron, incense, and myrrh. However, these pills are no longer used at present, and the herb is generally only applied externally presently.

Healing Properties and Indications
The root of the hound’s tongue plant contains alkaloids (cynoglossine), a toxic glycoside (consolidine), a bitter component (cynglossidine), mucin, allantoin, and tannin. Its leaves are especially rich in allantoin and tannin. Allantoin is an emollient and healing substance that is part of the composition of several creams and pharmaceutical preparations.
Hound’s tongue has astringent and soothing properties. In external application, it has emollient (calms the inflamed skin mucosa) properties and wound healing properties due to its content in allantoin.
This plant has been used as an infusion for antidiarrheic and pectoral purposes, but since it is harmful to the liver, its external use only is recommended. However, its main application is in external use, as a cicatrizant for skin cracks, burns, torpid ulcerations, and difficult healing wounds.
Hand baths with a decoction of hound’s tongue soothe and hydrate the skin and hands and are very useful for dry skin due to cold or chemical products.
