In this segment, Dr. Caroline Williams discusses the therapeutic benefits of infrared light, emphasizing its role in wound healing. She distinguishes between red light, which promotes collagen production, and near‑infrared light, which is effective for repairing damaged tissue. Williams cites a striking anecdote where near‑infrared treatment was applied to patients with toe gangrene who were slated for amputation; after a brief exposure, blood flow was restored, the tissue repaired, and the amputations were avoided. She also references LifeWave patches as a related modality, noting that infrared light complements these technologies in supporting healing.

In addition to the LifeWave patches, infrared, uh, infrared light is very beneficial for wound healing. Um, and you know, I haven't— I have a video that shows that, um, they were using the red light, or not just red light because there's, there's red light for collagen production and there's a near infrared for wound healing. And the near infrared, they were literally using it on people who had gangrene in like their toes and they were scheduled for amputation. And, uh, just with a short use of the near-infrared, and they didn't have to have their toes amputated. The blood flow came back and the repair happened and they were able to keep their toes. So it's pretty dramatic.
