Goji berries in a bowl

Gaining widespread popularity in recent years, the goji berry plant, whose fruit are colored bright orange-red, is considered the "fountain of youth." Along with the health benefits, however, adverse reactions are also found with the excessive consumption of this fruit.

Goji berry has two subspecies with quite similar qualities. These berry plants are widely found in temperate and subtropical regions. They are grown in China mainly for their incredible health benefits. Apart from China, they are also widespread in the regions of Tibet and the Himalayas, as well as in Mongolia.

Although the bright, orange fruit have been used by the Chinese and Tibetans for centuries for their medicinal properties, the tiny fruit have recently captured the world's attention for their supposed effects on human longevity.

If consumed in moderation, goji berries only have a positive effect on a person. However, if they are consumed in larger quantities, they are capable of causing some side effects.

People with pollen allergies should avoid these fruit or consult a doctor before consuming them. Side effects in this case include difficulty breathing, hives, nausea and dizziness.

Goji berries

Goji berries contain the alkaloid atropine. Overdosing on it can cause vomiting, blurred vision, dry mouth, and confusion.

The serious side effects of taking various goji berry extracts occur as a result of the fruit's interactions with certain medications, especially those for blood pressure. An abnormal drop in blood pressure or hypotension may occur.

Also, the fruit affects people taking medication for diabetes. It may cause the blood sugar level to drop and symptoms such as dizziness and fainting.

Apart from blood pressure and diabetes medications, this fruit can interact with warfarin. It is an anticoagulant - a drug that prevents the formation of blood clots in the blood vessels. Taking these fruit in this case increases the risk of bleeding.

Goji berries have a high selenium content. Although selenium is an important trace element for the body, in rare cases, its high doses lead to the development of birth defects and reduced fertility in women, nerve damage and/or gastrointestinal problems.
