Side Effects

Tea and tincture of hyssop are unlikely to cause adverse effects.9 Although, the volatile oil, particularly its constituent pinocamphone, has been reported to cause seizures in laboratory animals as well as in humans when taking more than 10 drops in a day or a child taking 2–3 drops over several days.10 For this reason, the volatile oil should be used with extreme caution and is not recommended for those with epilepsy or any other seizure disorder. The herb is not recommended during pregnancy.11
