Worn knee joint? Drink two cups of mint tea a day
Half of the subjects were given leaves of regular mint - scientific name: Mentha spicata. The other half received leaves of a special variety, which the researchers call highros A spearmint plant clone 700B. This variant was created by co-author Laima Kott, and also holds the patent for this plant.
The researchers published earlier in vitro research [BMC Complement Altern Med. 2010 May 11;10:19.] and an animal study [J Vet Pharmacol Ther. 2012 Oct;35(5):495-502.] in which extracts of highros A spearmint plant clone 700B reduced cartilage degradation.
Although this increase was not statistically significant, the researchers think it says something. "We postulate that, at week 16, the high-rosmarinic acid spearmint tea group was starting to experience improvements in physical function related to their reduced pain," they write.
"This is important, given the lack of effective osteoarthritis treatment options and reliance on pain medications to which adherence rates are low. Failure to adequately manage osteoarthritis pain and symptoms can negatively impact social interactions and quality of life and leads to increased personal, healthcare, and economic costs."
"In this study, individuals with osteoarthritis of the knee who consumed 600mL of high-rosmarinic acid spearmint tea daily for 4 months showed significant improvements in pain scores and physical function. Therefore, adults with knee osteoarthritis may benefit from including high-rosmarinic acid spearmint tea in their daily routine."
"Larger and longer-term studies are required to validate the high-rosmarinic acid tea as a complementary osteoarthritis treatment."
In a capsule Rosmarinic Acid Extract of Life Extension is 100 milligrams of rosmarinic acid.
