Healing Properties and Warning

soapwort extract skin benefits
When in the countryside, rubbing your hands with the soaproot plant flowers is a good method to wash them with no soap.

The whole plant, mainly its root and rhizome, contains a saponin called saporrubine, with expectorant, diuretic, cholagogue, and depurative properties. The saponins can dissolve fats into the water, producing foam.

Its most important action is the expectorant because of the ability to make the bronchial secretions more fluid. However, being effective with respiratory afflictions, given its toxicity when internally used, it has been substituted with more safe plants. In external application, it is helpful to combat skin eczema and rashes and for washing delicate hair.

WARNING! Do not exceed the recommended dose for internal use since this plant may produce poisoning.
