Can drinking too much goji berry cause "heatiness"?

In general, excessive consumption of goji berries may lead to "heatiness." The detailed explanation is as follows:

Goji berry is a common traditional Chinese medicinal herb known for its effects of nourishing the liver and kidneys and improving vision. Goji berries are slightly warming in nature, and moderate consumption usually does not cause heatiness. However, overconsumption may lead to such symptoms. Goji berries contain certain amounts of active components like polysaccharides; excessive intake may increase the body's metabolic burden, resulting in internal heat and manifesting as symptoms of heatiness, such as dry or bitter mouth, oral ulcers, sore throat, red and painful eyes, and constipation. Individuals with a naturally hot constitution or yin deficiency with hyperactive fire are particularly prone to developing heatiness after consuming too many goji berries. The risk of heatiness further increases if goji berries are consumed together with other warming foods, or if one is exposed to hot environments, overworked, or under emotional stress.

In daily life, individuals can adjust their intake according to their body constitution by combining goji berries with cooling ingredients such as chrysanthemum flowers or honeysuckle. If symptoms of heatiness occur, consumption of goji berries should be stopped promptly, and appropriate measures taken to relieve symptoms—such as drinking more water, eating more vegetables and fruits, and ensuring sufficient sleep.
