Interaction Details
Linagliptin, Metformin Hydrochloride is classified as belonging to the following category: Antidiabetes Drugs
Theoretically, taking gymnema with antidiabetes drugs might increase the risk of hypoglycemia.
Gymnema reduces blood glucose levels in some human and animal research. In human studies, it has been shown to enhance the blood glucose lowering effects of hypoglycemic drugs. However, other research in adults with prediabetes or metabolic syndrome suggests that gymnema does not reduce fasting levels of blood glucose. Until more is known, monitor blood glucose levels closely.

Gymnema Overview
Gymnema (Gymnema sylvestre) is a plant species native to India and Africa that has been used traditionally in Ayurvedic medicine for centuries to treat a range of conditions, including diabetes, obesity, and digestive problems.
Gymnema is thought to work by inhibiting the absorption of sugar in the intestines and by increasing the production of insulin in the pancreas. If applied topically to the tongue, it reduces the sweetness and bitter sensation of foods, which may deter excess sugar intake (the plant is sometimes referred to informally as 'the sugar destroyer').
One of the most popular natural medicines utilized for dietary supplements, an extract of the leaf (Gymnema leaf extract) is the most often standardized for use, although the root can be used as well.
