In older studies, mono-preparations of extracts were applied in daily dosages equivalent to 3 times 14.4 mg benzyl mustard oil. The dosage for combinations depends on the contribution of the herb in the specific combination, which in each case must be documented.

9. Overdosage

Overdosing can cause albuminuria, which apparently is due to damage to the glomerulus and tubulus system.
