Interaction Details
There were no interactions found between Modafinil 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.
Burdock Overview

Modafinil Overview
-
Modafinil is used to treat excessive sleepiness caused by narcolepsy (a condition that causes excessive daytime sleepiness) or shift work sleep disorder (sleepiness during scheduled waking hours and difficulty falling asleep or staying asleep during scheduled sleeping hours in people who work at night or on rotating shifts). Modafinil is also used along with breathing devices or other treatments to prevent excessive sleepiness caused by obstructive sleep apnea/hypopnea syndrome (OSAHS; a sleep disorder in which the patient briefly stops breathing or breathes shallowly many times during sleep and therefore doesn't get enough restful sleep). Modafinil is in a class of medications called wakefulness promoting agents. It works by changing the amounts of certain natural substances in the area of the brain that controls sleep and wakefulness.
