On Star Trek when someone is injured, they are taken to sick bay where the doctor uses a laser to heal the patient instantly. We make those (just not quite as instant).

The treatment is called Photobiomodulation (PBM Therapy) previously known as Low Level Laser Therapy (LLLT) and is considered by many scientists to be "a new branch of medicine" (Dr Roberta Chow MD PhD).

Light (within certain parameters) can regenerate tissue, reduce inflammation and reduce pain. It does this by increasing cellular energy and reducing oxidative stress. These effects have been tested in over 700 clinical trials (RCT's) and thousands of laboratory studies and published in many leading journals including The Lancet, BMJ, Nature, PNAS, Spine, Muscle and Nerve, Pain, Stroke etc.

Dedicated private PBM clinics are being born every month to meet public demand for pain relief and the former head of tissue viability for Scotland Lydia Jack demonstrated that the laser paid for itself with the first patient she treated.
