What is it?
The safety and efficacy of lycium for chronic diseases has not been established.
Lycium berries, commonly referred to as goji berries, are used in traditional medicine to treat inflammation, skin irritation, nose bleeds, aches, and pains. Lycium is also used as a sedative. In Chinese medicine, it is commonly used with other botanicals for poor vision, anemia, and cough. As Goji berries, they are marketed as a superfood that are high in antioxidants.
Lab studies have identified polysaccharides from the plant that may improve immune response and effects of radiation therapy. Other experiments suggest Lycium may inhibit the growth of some cancer cells.
In humans, a few small studies suggest potential benefits in helping to lower cholesterol or blood sugar. However, data are limited and it has not been studied for cancer prevention or treatment. Well-designed clinical trials are needed to determine any benefits Lycium may have against chronic diseases.

What else do I need to know?
Do Not Take if:
You have lipid transfer protein food allergies: Hypersensitivity reactions have been reported in patients at high risk of plant-based food allergies.
You are taking warfarin or other anticoagulants: A few cases of elevated INR were reported in patients on anticoagulant therapy following consumption of Lycium products.
You are taking CYP 3A4, 2C9, or 2C19 substrate drugs: Lycium extract may influence how these drugs are metabolized.
