Synopsis

Source of validity: Traditional
Rating (out of 5): 2

Black pepper (Piper nigrum) has been traditionally used in various cultures for a variety of digestive complaints, including nausea and vomiting. In Ayurvedic and traditional Chinese medicine, black pepper is considered a carminative and digestive stimulant, and its use for gastrointestinal discomfort, including nausea, is well documented in historical medical texts. The rationale is that the pungent compounds in black pepper, primarily piperine, are thought to stimulate the secretion of digestive enzymes and increase gastrointestinal motility, which might help alleviate symptoms like nausea. However, modern scientific research specifically targeting black pepper’s efficacy for nausea and vomiting is limited and not robust. Some studies have explored black pepper aromatherapy or its compounds for post-operative nausea, but the results are preliminary and often confounded by the use of black pepper in combination with other essential oils. While laboratory studies suggest that piperine may have effects on gut motility and neurotransmitter activity, clinical trials directly supporting black pepper’s use for nausea are sparse. Thus, the evidence supporting its use is primarily traditional, with a modest rating of 2 out of 5 due to limited scientific validation.
