Is Comfrey Leaf° COSMOS-approved?
It can fit COSMOS-natural or COSMOS-organic when grown and processed under approved methods, especially with water, ethanol, or glycerin extraction. From a Green Chemistry view, the renewable feedstock is favorable, while alkaloid variability adds a testing and quality-control burden.
How does Comfrey Leaf° work chemically?
This material is a botanical leaf powder or extract containing mucilage polysaccharides, phenolic acids, tannins, allantoin, and potentially pyrrolizidine alkaloids.
