Can Lycium barbarum (goji berries) be steeped in water together with tea leaves for consumption?
Generally speaking, goji berries can be steeped in water together with tea leaves. The detailed explanation is as follows:

Tea contains polyphenols and caffeine, which can refresh the mind, relieve fatigue, and provide antioxidant effects. Goji berries are rich in various vitamins and minerals, which can nourish the liver and kidneys, improve vision, and promote a healthy complexion. Combining both in water steeping can enhance the flavor of the beverage while also providing health benefits, making it suitable for individuals seeking to relieve fatigue or alleviate eye discomfort.
However, tea tends to be cooling in nature, especially green tea, which may cause discomfort for individuals with cold body constitution or sensitive stomachs. Goji berries are generally neutral to slightly warm in nature and have nourishing properties; excessive consumption may lead to heatiness or bodily strain. Therefore, individuals with different body constitutions should adjust the ratio of tea to goji berries according to their own conditions to avoid health issues caused by improper combination.
When consuming, it is important to control the concentration and quantity to avoid excessive intake of caffeine or nutrients, which could place an additional burden on the body.
