Researching plants that benefit our skin go into each batch I have formulated .Dandelion,Plantain,Comfrey,Elderberry,Milk Thistle,Nettle,Echinacea just to name a few. Infusing the plant/herbs in Sunflower Oil then extracting the properties giving the soap its original character with herb colouring madder root,spirlina,kelp, and many clays.No micas are used as it’s marked natural but all I can say is look up how it’s extracted and what is in the original form. Small batches only 8 bars per batch and 6 weeks to cure .
