Hyoscyamus niger, commonly known as Khursani Ajawain, is a plant known for its historical use in traditional medicine. However, it is important to note that henbane contains toxic alkaloids, particularly hyoscyamine, scopolamine, and atropine, which can be dangerous in high concentrations. As a result, the use of Khursani Ajawain extracts should be approached with extreme caution, and it's crucial to consult with a qualified healthcare professional before considering any form of supplementation or medicinal use.
