Chamomile
Chamomile is a flower containing powerful antioxidants to boost immunity and treat several health conditions, including nausea. Like fennel powder, chamomile helps to relax muscles in the gastrointestinal tract; thereby, preventing bloating and discomfort in the stomach. A study [10] showed that chamomile helped to relieve post-surgery nausea in sixty-five cancer patients. Drinking chamomile tea helps to reduce multiple GI conditions like cramps, gas, bloating and nausea.
Cannabidiol Oil
Cannabidiol oil is sourced from cannabinoids [11] CBD, a chemical compound found in the cannabis plant. Cannabinoids help treat nausea and vomiting by regulating the serotonin hormone, which transmits signals to the cells responsible for vomiting. Research has shown that this chemical compound reduces nausea caused by medication or treatments like chemotherapy.
Antiemetic
An antiemetic is an anti-nausea drug [12]. Examples include; prochlorperazine, promethazine, metoclopramide, antihistamines, and vitamin B6 supplements. These drugs interfere with the nerve transmissions, which send signals that cause feelings of nausea. There are antiemetic drugs [13] to relieve nausea caused by motion sickness, gastroenteritis, and pregnancy. Chemotherapy and post-operation drugs are also standard.
