According to Wehner, one of the product’s special strengths is that it combines modern research with ancient wisdom. “Our customers are very happy that we managed to pack a lot of traditional healing lore into our modern extract,” she says. People throughout Germany have long relied on comfrey, which in various regions is referred to by local names that reflect its healing properties.

Pharmacologists found out long ago that the extract’s key active ingredients are allantoin, rosmarinic acid, and various types of polysaccharide. However, clinical studies will continue to be conducted to determine the exact effects of the analgesic and anti-inflammatory ointment on certain ailments. The specialists at Merck all agree that the comfrey-based medication will continue to generate good news, and studies focusing on other muscle and joint ailments are already under way. Modern medical researchers are thus providing hard facts that confirm the lore of ancient doctors and Native American healers.
