Description of intervention(s) / exposure
The intervention will occur at one single time point and the study duration is for one single calendar day.
Intervention Groups 2 and 3 will receive standard care (including prescribed anti-emetic medication) in addition to a highly refined, standardised ginger root powder supplement in capsule form for oral consumption as a single dose (one time only) at the commencement of chemotherapy infusion. The ginger extract is manufactured by an independent company that will have no involvement in the study. The 300mg ginger root powder capsule will be standardised to contain 7% bioactive compounds (gingerols and shogaols).
Group 2 (low dose ginger) will receive one capsule (300mg of ginger root, 21mg of bioactive compounds [gingerols and shogaols]).
Group 3 (high dose ginger) will receive two capsules (600mg of ginger root, 42mg of gingerols/shogaols).
All participants will be required to have fasted (food and drinks) for 4 hours prior to the test commencing (water is okay). All participants will be given a meal to consume after 30-minutes of baseline data has been captured. This meal will be standardised to contain similar energy and macronutrient contents and will meet any special dietary requirements or preferences of participants.
Adherence to supplement consumption will be noted by the investigator who administered the intervention and test. Adherence will be noted as the number of supplement capsules consumed as per the protocol (0, 1, or 2 capsules).

Summary
Brief summary
This study aims to gather evidence on the mechanisms of action and optimal dose of ginger for chemotherapy-induced nausea and vomiting (CINV), one of the most distressing and common side-effects for people undergoing chemotherapy. Who is it for? You may be eligible for this study if you are an adult scheduled to undergo intravenous (IV) chemotherapy for any type of cancer, and have been deemed to be at moderate to high risk of nausea and vomiting. Study details Participants will be randomly allocated to receive either standard care, or low dose or high dose oral ginger supplements at the beginning of chemotherapy infusion. This will occur on a single test day, with outcome data collected using a novel technique called Body Surface Gastric Mapping (BSGM) in the baseline (fasting) states as well as during chemotherapy infusion. It is hoped that findings will guide the optimal ginger dose to improve the management of CINV and assist in the future application of BSGM as a non-invasive, low cost, and quick measure of CINV treatments.
