Why would herbs be supplied in combination blends?
Historically, the people who studied, catalogued and used herbs in treating people would use them in combinations. Traditional herbalists knew which combinations of herbs, when prepared in certain ways, would yield the results they were interested in. An herbalist would take several different plants, prepare them together as a tea, poultice, blend of dried powders, etc. and administer them. Drawing on this rich history of application improves can improve the successes of modern treatments as well.
