Can an enlarged heart be treated with Chinese medicine?

Not necessarily.
Generally speaking, treatment of enlarged heart is based on controlling the cause, dealing with the primary lesion, delaying the progression of the disease, preventing and controlling complications, and diuresis. Chinese herbal treatment can improve the symptoms by supporting the original cause and activating blood circulation. However, there is no obvious therapeutic evidence for Chinese herbal medicine in the treatment of enlarged heart, and most Chinese herbal medicines have damaging effects on the liver and may further aggravate the circulatory burden, so they should be used with more caution and can be appropriately treated with a combination of Chinese herbal medicine and Western medicine under the guidance of a regular doctor and closely monitored regulation, but scientific and definitive treatment should still prevail.
