Glycetracts are made without using alcohol for the extraction of the herb. They are made from Glycerol, distilled water and herbs. The glycerol used is vegetable sourced. Glycetracts are suitable for people who need to avoid any alcohol (e.g. young children, recovering alcoholics and those with liver distress).
According to Mountain Rose Herbs, some of the controversy stems from its historic use and recent testing:
"Comfrey’s use in Chinese traditional medicine spans over 2000 years. All Materia Medica from the Middle Ages forward carried descriptions on the uses of comfrey. Comfrey baths were very common during the Middle Ages. Comfrey is widely known as “one of nature’s greatest medicinal herbs”, and has appeared in the U.S. Pharmacopoeia, as well as in herbals and compendiums around the world. Recently, reports of the toxic effects of pyrrolizidine alkaloids in comfrey have led some herbalists to be wary of using it internally. PAs in extremely large doses or over long periods of time may cause potentially fatal damage to the liver. Many leading herbalists and traditional healers question the warnings, pointing to laboratory tests that show only minute levels of PAs in random samples of comfrey preparations."
A paragraph from Wellness Mama's website.
"With regards to the warnings that comfrey can cause cancer and liver disease, most herbal practitioners point out that those results were from studies that isolated the pyrrolizidine alkaloids and fed or injected them into animal subjects in doses far higher than any typical usage of comfrey leaf, and that comfrey leaf has been regularly ingested by thousands of people around the world without reported ill effects.”
Comfrey leaf externally is great for healing wounds and broken bones. It is high in Calcium and Vitamin C ans simulates the healing activity.
Many of the beneficial properties of comfrey are attributed to its high content of allantoin, a substance that helps promote new skin cell growth, along with other substances that may work in reducing inflammation and maintaining healthy skin. Comfrey ointments have been used to help heal bruises and pulled muscles and ligaments.
