Interaction Details
There were no interactions found between Topotecan and Burdock. This does not mean the potential for an interaction does not exist, however. There is often a lack of studies and data surrounding traditional medicine, especially concerning drug interactions, so it is important to always consult your provider before making any changes to your medication regimen.
Pharmacist Analysis
While burdock root has been traditionally used in herbal medicine for a variety of health conditions, its potential interactions with medications have not been well studied. Currently, there is only limited information available.
Burdock contains a variety of different compounds, includin arctigenin, arctiin, beta-eudesmol, caffeic acid, chlorogenic acid, diarctigenin, inulin, lappaol, tannin, trachelogenin, and sitosterol-beta-D-glucopyranoside, all of which can have a wide range of effects.
One of the only theoretical interactions that have been suggested is with anticoagulant and antiplatelet medications, as burdock root may have mild blood-thinning effects. This has only been seen in animal studies, however.
Further research is needed to fully understand the potential interactions between burdock root and medications.
