The tobacco plant was given its name by Jean Nicot, a French ambassador to South America who introduced it into Europe around 1560. However, the plant was used by Native Americans long before this date. Tobacco contains nicotine, which is a poison that can cause severe nausea, vomiting, sweating, dizziness, and palpitations. The homeopathic remedy is used to treat such symptoms. Tabacum is mainly given for nausea, vomiting, and motion sickness. Symptoms come on suddenly and include excessive saliva, pain, chilliness with perspiration, anxiety, and vertigo. The least motion aggravates the nausea and vomiting. It is also good for severe nausea that accompanies other ailments.
