It is used to sooth muscle aches and insect bites. It is used for arthritis and ulcers. It helps our skin stay healthy and youthful looking. Comfrey salve applied to an area infected with Staphylococcus quickly kills the bacteria.

It helps regulate blood pressure. It is sometimes used for lupus, cancer and sinus problems. It is used for lung problems and joint inflammation.

Cautions: Many countries have banned the use of comfrey for internal treatments because some studies indicate that it can cause liver cancer. Some herbalist say the studies were flawed because they used concentrations of one ingredient from comfrey in a dose much too large to represent the amount a person would get when taking the herb. Nevertheless, t is best to limit the use of comfrey to external treatments.
