The majority of soaps contains caustic soda that, as it is known, is aggressive for skin health. Consequently the use of this type of these "more industrial" soaps produces inadequate results in the skin, that manifest as anomalies, such as dry skin, dermatitis, dandruff, hair loss, etc. However, there is the possibility of making a homemade soap, natural and ecological, without soda, but based on medicinal herbs.
HERBAL ORGANIC SOAP
Common Soapwort (Saponaria officinalis) is a lively grass from the family of carnations (Caryophyllaceae) up to 1 m in height. Noted for its beautiful pale pink flowers, is very abundant along roadsides, cultivated fields, river banks or ditches can be found from spring to late summer. Wherever there is sufficient moisture, it forms dense clumps with many stems that grow from an underground rhizome that is very difficult to eradicate and that sometimes makes it an invasive plant.
It is a plant that has been used extensively in herbal medicine in many diseases such as rheumatism, the itching of the skin, excess of cholesterol, eczema, etc. However, in the section that concerns us now, this plant stands out because it has been used since ancient times as soap. Its scientific name of saponaria, means "the one that produces soap." The reason for this property is due to its wealth of saponins. Saponins are a class of glycosides characterized by their ability to produce foam in contact with the water , therefore, they are considered as components with detergent properties.
Common soapwort is one of the richest plants in saponins, therefore it has been used to wash clothes and wool. People placed a bunch of rhizomes in a bowl with water and let the clothes soak overnight. The next day, they rinsed it and the clothes were clean because the foam generated by the saponins of this plant removed the dirtiness. In fact, it is also known as Lanari because the same procedure was used to wash the wool.
