The National Library of Medicine conducted a placebo-controlled, double-blind randomized trial...
Showing that those who used comfrey lowered their back pain by 95.2% in five days, compared to a 37.8% reduction with the placebo.
And those who used the comfrey reported a 33% reduction in pain within one hour!
So not only not only is comfrey a natural pain reliever - but it works FAST!
This is due to the comfrey's natural compounds like:
• Allantoin (promotes the healing of tissues)
• Rosmarinic acid (anti-inflammatory)
• Mucilage (muscle relaxing and soothing effects)
These compounds work together to naturally relieve your pain, lower inflammation, and speed up the healing process.
Another 2007 clinical study from Phytomedicine found that comfrey extract containing rosmarinic acid significantly reduced inflammation and pain in patients with acute back pain.
And there's hundreds of more studies with similar results.
