Definition: In the Bible, a "anticonvulsant" refers to a substance or medication designed for controlling seizures (compulsive). This term was used by Jewish sages who believed that it could help prevent or treat severe epilepsy, especially those with complex medical conditions like multiple sclerosis or brain damage. These substances were often made from a variety of plant materials and were highly regarded for their ability to slow down the progression of seizures, which prevented the risk of further harm.
