According to Dr. Peter A.G.M. De Smet of the Netherlands, "if an herb caused an adverse reaction in 1 in 1,000 users. A traditional healer would have to treat 4,800 patient's with that herb (i.e., one new patient every single working day for more than 18 years) To have a 95 percent chance of observing the reaction in more than one user." Verify this calculation by finding the probability of observing more than one reaction in 4,800 patients, given that 1 in 1,000 has a reaction.
