“Ursolic acid is present in many plants, such as Mirabilis jalapa, as well as in many fruits and herbs used in daily life e.g. apples, basil, bilberries, cranberries, elder flower, peppermint, rosemary, lavender, oregano, thyme, hawthorn, and prunes). Apple peels contain large quantities of ursolic acid and related compounds.” Wikipedia
An April 2020 study by the Sidney Kimmel Medical College at Thomas Jefferson University said,
"Although the evidence is preliminary - our data is from animal models of disease - it's encouraging to see a compound that both halts and repairs damage in [multiple sclerosis] MS, in the lab."
"Many experiments have looked at mice in the acute phase, when disease is just starting or at the peak."
“Instead, we tested whether this compound was effective in chronic disease, once there has already been chronic damage to tissues of central nervous system."
"It's not a cure, but if we see a similar response in people, it would represent a significant change in quality of life. And most significantly, it's a reversal, which we really haven't seen before with other agents at such a late stage of disease”
