Comfrey's use dates back centuries to at least the time of the ancient Greeks. During the Middle Ages comfrey was a widely cultivated herb found extensively in the gardens of monasteries. Throughout the 1700's and 1800's comfrey was also a popular herb grown in many gardens across Europe as well as America. Sometime during the late 1970's however research revealed that comfrey when taken internally can cause severe liver damage so it has lost popularity and internal use is even banned in many countries. Applications in the from of ointments, poultices, or creams are still considered safe though. Comfrey can still be found growing wild in central Europe, and the eastern United States as well as a few western states.
Plantain is quite possibly one of the first herbs to make its way to America from Europe. Originally brought over by the Puritan colonists plantain was called "white man's footprint" by the native Americans because of its ability to thrive where ever the new colonists had planted it. Plantain grows world wide now often thought of as a weed, it does however have some powerful medicinal benefits that shouldn't go unnoticed. Plantains ability to heal wounds such as cuts, burns, and swelling have been noted all the way back to medieval Europe. In addition to being a powerful wound healer plantain also shows promising results for treating ailments such as edema, jaundice, ear infections, ringworm, and shingles. The main constituents responsible for plantain's healing properties are aucubin, allatonin, mucilage, flavonoids, caffeic acid, and alcohols found in the wax of plantain's leaves. All these combine to make it a must have in your herbal first aid kit.
