An electromagnetic therapy apparatus includes: upper magnetic heads mounted on a frame; lower magnetic heads mounted in a treatment bed, wherein each of the lower magnetic heads is connected to a rotary power supplier and is driven to rotate individually thereby, the lower magnetic heads drive the upper magnetic heads to rotate by magnetic force coupling; therapy clothes provided on a treatment bed and connected to a physiotherapy liquid collection tank through a circulation pump; self-heating tourmaline slices or metal clamps mounted in the therapy clothes; and a high-frequency heating induction coil mounted in the treatment bed and connected to a high-frequency power supplier. Auxiliary physiotherapy liquid includes: basic liquid; and a traditional Chinese medicine additive. By applying a magnetic principle of Western medicine on human bodies, anti-cancer and blood-thinning effects can be achieved. With high-speed metabolism, utilizing the traditional Chinese medicine can accelerate a recovery process.
