Indian Chrysanthemum (Chrysanthemum indicum) has a long history of use in traditional medicine systems, particularly in Ayurveda and Traditional Chinese Medicine (TCM). Traditionally, it has been used for a variety of ailments including fever, headache, and inflammation. There are references in some traditional texts to its use for digestive complaints, which may include symptoms like nausea and vomiting, although these are not its primary indications. The flowers are believed to have cooling and calming properties and may be included in herbal formulations for their mild antiemetic (anti-nausea) effects, often alongside other herbs.

However, scientific validation for the use of Indian Chrysanthemum specifically for nausea and vomiting is sparse. Most of the pharmacological studies have focused on its anti-inflammatory, antioxidant, antimicrobial, and hepatoprotective properties. There is a lack of well-designed clinical trials or robust preclinical evidence directly examining its efficacy for nausea or vomiting. As such, the evidence supporting its use for this indication is primarily traditional, and the strength of that evidence is weak, meriting a low rating.
