Ginger: The Everyday Root That Eases Nausea & Pain
Ginger: The Everyday Root That Eases Nausea & Pain
Queasy stomach before a flight to KL, or a swollen knee after your Saturday badminton game? There's a good chance someone's already told you to try ginger — and it turns out that advice has real science behind it.
What Is Ginger?
Ginger is the knobby underground stem, or rhizome, of the Zingiber officinale plant — the same one behind the fiery kick in teh halia and the fragrance in your grandmother's chicken soup. It's been used in Indian and Chinese traditional medicine for thousands of years, long before science caught up to explain why.
The reason ginger tastes and smells the way it does comes down to compounds called gingerols and shogaols. Gingerols are the main bioactive component of ginger and research has indicated that gingerols have anti-inflammatory and antioxidant properties. When ginger is cooked or dried, gingerols convert into shogaols, and their health advantages surpass those of gingerols. This is part of why dried ginger powder in a curry paste can feel different from a slice of fresh ginger steeped in hot water.
Why Do People Take It?
Settling Nausea and an Upset Stomach
This is ginger's best-known and best-studied use. Research shows that ginger may be helpful for nausea and vomiting associated with pregnancy. A large review of over a hundred clinical trials found similarly encouraging results for digestive-related nausea, though the picture is more mixed for other types. Most studies of ginger for motion sickness haven't shown it to be helpful, and it's uncertain whether ginger is a helpful addition to standard treatments for nausea and vomiting associated with cancer chemotherapy. For the average person feeling seasick on a ferry to Batam or queasy after too much economy rice, ginger tea or ginger candy remains a reasonable, low-risk thing to try.
Calming Joint Discomfort
If you've noticed uncles and aunties reaching for ginger compresses for aching knees, there's a reasonable basis for it. Ginger dietary supplements might be helpful for symptoms of knee osteoarthritis, but much of the research has been of poor quality. Interestingly, ginger used topically, applied to the skin, has not been shown to be helpful for knee osteoarthritis symptoms — so the effect, where it exists, seems to come from eating or drinking it rather than rubbing it on.
Easing Period Cramps
Research suggests that ginger dietary supplements might be helpful for reducing the severity of menstrual cramps. Some studies have compared ginger's effect on period pain to common pain relievers with reasonably similar results, which is worth knowing if you'd rather try a food-based option first before reaching for medication.
Supporting Digestion and Fighting Everyday Bugs
Beyond nausea specifically, ginger appears to help move food through your gut more efficiently, which is part of why it's traditionally served alongside heavier, oilier meals like bak kut teh. Laboratory research has also found that the health benefits of ginger include antibacterial, antiviral, antioxidant, anti-inflammatory, antinausea, and anticancer properties, though the exact mechanism is not yet fully understood, with research showing that several active compounds in ginger have biological activity. Much of this antimicrobial and anticancer research is still early-stage, done in labs or animals rather than large human trials, so it's promising rather than proven.
Bioavailability & Absorption
Ginger's active compounds don't get absorbed by your body all that easily on their own. Gingerols are fat-soluble and break down fairly quickly once they're inside you, which is one reason researchers have looked at whether pairing ginger with other ingredients might help.
There's some early lab evidence that ginger extract, alongside spices like turmeric and black pepper, may enhance the uptake of certain other nutrients in the gut, though this research is still preliminary and mostly done outside the human body. In everyday terms, this simply reinforces something Southeast Asian cooking already does instinctively — ginger, garlic, turmeric, and chilli rarely appear alone in a dish. Cooking or drying ginger also shifts its chemistry, converting more of the gingerol into shogaol, which may explain why traditional preparations often call for dried or cooked ginger rather than raw.
Safety Basics
Ginger has been used safely in many research studies where it was taken orally as a dietary supplement, and ginger products may also be safe for topical use. That said, it isn't entirely without side effects. Ginger can have side effects such as abdominal discomfort, heartburn, diarrhea, and mouth and throat irritation when taken orally. These effects tend to show up more with concentrated ginger supplements than with ginger used as a cooking ingredient or in tea.
A few groups should be more careful. Ginger may increase the risk of bleeding, especially if you also take blood-thinners such as warfarin or aspirin, so check with your healthcare provider before using ginger supplements. Because ginger encourages the release of bile from the gallbladder, it is contraindicated for patients with cholecystitis or cholangitis, and ginger also interacts with warfarin and potentially other anticoagulant drugs. If you're pregnant, the use of ginger dietary supplements during pregnancy may be safe, but as with all herbal supplements, if you're considering using ginger while pregnant, consult your health care provider. Little is known about whether it's safe to use ginger while breastfeeding. If you're a busy PMEB professional juggling supplements alongside prescribed medication for blood pressure or diabetes, it's worth a quick check with your pharmacist too, since ginger can interact with some of these drugs.

Final Thoughts
Ginger isn't a miracle cure, but it's one of the rare traditional remedies where the science genuinely backs up a good chunk of the folklore — particularly for nausea, period cramps, and possibly joint comfort. For most people already eating it regularly in hawker food, home cooking, or a warm cup of teh halia, that's a comforting bit of validation.
Where it gets more complicated is with concentrated supplements, especially if you're pregnant, on blood thinners, or managing a chronic condition — that's when a quick word with your doctor or pharmacist matters more than usual. For everyday use in your cooking or as an occasional tea, ginger remains one of the easiest, most accessible ingredients to lean on.
