Anxiety over aging in China has boosted an anti-aging market bursting with expensive treatments, such as therapeutic or double filtration plasma exchange, ozone treatments, stem cell injections and the so-called life extending "miracle drug" rapamycin. However, while these drugs and procedures are intended to treat human illnesses, such as kidney disease, autoimmune deficiency and chronic hepatitis, they have yet to be approved for anti-aging and anti-cancer use. Meanwhile, despite new rules unveiled by Chinese regulators, these therapies with obscure names and unclear effects on healthy bodies are still being provided by clinics, especially private ones. Experts say that aging should not be treated as a disease, but rather an irreversible natural process. A healthy lifestyle, marked by a balanced diet, regular exercise, sufficient sleep, no smoking and moderate alcohol, is more effective than any anti-aging therapy.
