Extract of comfrey root can be used to quickly and effectively relieve chronic back pain, latest study results suggest.
German researchers studied 120 people with upper and lower back pain. Half used an ointment containing extract of comfrey root – 4g applied three to five times a day - and the rest used a placebo.
After five days, the researchers found that those who used extract of comfrey root ointment had a 95% reduction in pain intensity, compared to just 39% of those who used a placebo. Comfrey root was also fast acting, relieving pain after just an hour, they said.
‘Comfrey root extract shows a remarkably potent and clinically relevant effect in reducing acute back pain. Reduction of pain and impaired movement was fast, and for the first time, a fast acting effect of the ointment has also been witnessed in this trial,’ the researchers said online in the British Journal of Sports Medicine.
