Ginger may reduce motion sickness symptoms in some people, but it hasn't been proven to be effective. Clinical studies have yielded conflicting results: in some studies, ginger reduced vomiting, cold sweats, or nausea, while in others, it was no better than placebo.
Ginger has indeed been studied as a nausea remedy, but the simple answer of "it helps with nausea" is overly simplistic. The most compelling evidence applies to mild to moderate nausea during pregnancy: systematic reviews show a reduction in nausea severity, while the effect on vomiting is less consistent.
Ginger does have some proven effects, but its benefits are far more limited than what popular articles and supplement advertisements often promise. The best-studied use of ginger is for reducing nausea during pregnancy.
Golden milk is a warm drink made from milk or a plant-based alternative with turmeric, often flavored with ginger, cinnamon, black pepper, and sweetener. It can be included in a regular diet, but there's no evidence yet to consider it a medicinal drink.
Curcumin is generally well-tolerated, but it cannot be considered a completely safe supplement. The most common adverse reactions are gastrointestinal: nausea, vomiting, heartburn or acid reflux, abdominal discomfort, diarrhea, and constipation.
Curcumin may indeed slightly lower glucose levels in people with prediabetes and type 2 diabetes, but it is not currently considered a proven treatment for diabetes or a replacement for antidiabetic drugs.
If you are taking warfarin, apixaban, rivaroxaban, dabigatran, edoxaban, heparin, or antiplatelet drugs such as aspirin or clopidogrel, do not start taking concentrated turmeric or curcumin supplements without consulting your doctor or pharmacist.
For most curcumin supplements, there's no proven "best" time of day—no significant difference has been established between morning and evening. Much more important are the form of the supplement, its method of administration, tolerability, and regularity.
