Interaction Details
Ibuprofen, Acetaminophen is classified as belonging to the following category: Anticoagulant/Antiplatelet Drugs
Theoretically, combining fever bark with antiplatelet or anticoagulant drugs might have additive effects; however, this has not been reported in clinical research.
Research in healthy adults shows that taking yohimbine, a constituent of fever bark, in doses of 8 mg or more, seems to inhibit platelet aggregation in vitro by binding to the alpha-2 adrenoceptor. The effects of fever bark itself are unclear.

Fever Bark Overview
Fever bark is the bark of the evergreen tree Alstonia constricta. The tree is native to tropical regions of Asia and is known for its tall, straight trunk and glossy, dark green leaves.
Alstonia constricta is used in traditional medicine to treat a variety of ailments, including fever, diarrhea, and infections. The bark of the tree contains several different alkaloids, including reserpine and yohimbine, which could cause serious side effects if misused. Unless you are under the direct supervision of a medical professional, the use of fever bark is not recommended.
Fever bark is sometimes referred to as Australian quinine, but it is not known to contain quinine.
