Most of the herbs in this class are potent and can induce vomiting. Black false hellebore is one such herb that is frequently used to induce vomiting of undigested foods and sputum in patients with epilepsy, apoplexy, thyroiditis, and lymphadenitis. This is done to remove any substances that may obstruct breathing or block the throat. Herbs in this category are typically available in powdered form.
If a patient fails to vomit within 10 to 20 minutes, they should stimulate their throat with a finger to induce vomiting. If the patient experiences continuous vomiting, they can be given ginger juice, cold rice soup, or cold water to stop the vomiting. After vomiting, the patient should consume soup or semiliquid foods and avoid greasy and difficult-to-digest foods.
Patients with swallowing difficulty, asthma, a cough, pulmonary tuberculosis, aneurysm, arteriosclerosis, hypertension, or heart disease should not consume this class of herbs. Additionally, young and old patients, pregnant women, and weak patients should avoid them.
