Intravenous or intravascular blood irradiation involves the in-vivo illumination of the blood by feeding low level laser light generated by a 1–3 mW helium–neon laser at a wavelength of 632.8 nm into a vascular channel, usually a vein in the forearm, under the assumption that any therapeutic effect will be circulated through the circulatory system.[3] The feasibility of intravascular laser irradiation for therapy of cardiocirculatory diseases was first presented in the American Heart Journal in 1982.[4] The technique was developed primarily in Asia (including Russia) and is not extensively used in other parts of the world. It is claimed to improve blood flow and its transport activities, but has not been subject to randomized controlled trials and is subject to skepticism. While there have been some calls to increase research on this topic,[1] others have called it "useless".
Ultraviolet blood irradiation may also be applied, though it involves drawing blood out through a vein and irradiating it outside of the body. Though promoted as a treatment for cancer, a 1952 review in the Journal of the American Medical Association[5] and another review by the American Cancer Society in 1970 concluded the treatment was ineffective.[6] Stephen Barrett, writing for Quackwatch, lists ultraviolet blood irradiation therapy as a questionable treatment.[7]
