Randy Fournier runs the largest network of nurseries in North America, the British Columbia-based PRT, which sold more than 600 million seedlings last year.

The study revealed after PRT, patients reported reduced back pain intensity.

To study the effects of pain attributions, they enrolled over 150 adults experiencing moderately severe chronic back pain in a randomized trial to receive PRT.

They found two-thirds of people treated with PRT reported being pain-free or nearly so after treatment, compared to only 20% of placebo controls.
