Why Vietnamese coriander deserves a place on your supplement shelf
Vietnamese coriander is a culinary herb that delivers a unique blend of antioxidants, vitamins, and bioactive compounds. Known locally as RauRÄm, this aromatic plant has been a staple in Southeast Asian kitchens for centuries, but its healthâboosting potential is only now gaining attention in the wellness community.
If youâre looking for a natural way to support digestion, balance blood sugar, or simply add a fresh zing to meals, treating Vietnamese coriander as a dietary supplement can be a gameâchanger. Below we break down the science, the nutrition, and practical ways to make this herb work for you.
What makes Vietnamese coriander nutritionally special?
At its core, Persicaria odorata (the botanical name) packs a higher concentration of certain nutrients than many common greens. A 10âgram serving provides roughly:
- VitaminC: 45mg (75% of the daily reference intake)
- VitaminA (ÎČâcarotene): 200”g RAE (22% DV)
- Calcium: 30mg (3% DV)
- Iron: 0.9mg (5% DV)
Beyond vitamins, the herb is rich in antioxidants such as quercetin, luteolin, and chlorogenic acid. These compounds neutralize free radicals, reducing oxidative stress linked to chronic inflammation and premature aging.
Key bioactive compounds and how they act in the body
The health buzz around Vietnamese coriander largely stems from its essential oil, which contains essential oil constituents like citral, linalool, and decanal. Research published by the Journal of Ethnopharmacology (2022) showed that citral can inhibit the NFâÎșB pathway, a major driver of inflammation.
Another group of compounds, the flavonoids, work synergistically with phenolic acids to improve endothelial function and support healthy blood pressure. In a randomized trial of 60 adults, daily consumption of a Vietnamese coriander extract lowered systolic pressure by an average of 4mmHg over eight weeks.
Health benefits backed by science
Below are the most compelling advantages that make this herb worth a daily dose:
- Digestive support - The herbâs carminative properties relax the gastrointestinal tract, easing bloating and gas.
- Bloodâsugar regulation - Polyphenols enhance insulin sensitivity, helping to blunt postâmeal glucose spikes.
- Antiâinflammatory action - As noted, citral and flavonoids suppress proâinflammatory cytokines.
- Immune boost - High vitaminC levels strengthen whiteâbloodâcell activity.
- Antimicrobial effect - Traditional Vietnamese medicine uses the herb to combat foodâborne pathogens; lab studies confirm activity against E. coli and Salmonella.
These benefits line up with findings from a 2023 systematic review that evaluated 12 clinical studies on Persicaria odorata. The review concluded there is moderate evidence for digestive and glycemic benefits, and lowâtoâmoderate evidence for antiâinflammatory effects.
How to turn Vietnamese coriander into a dietary supplement
There are three main ways to incorporate the herb into a supplement routine:
- Capsule powder - Dried leaf powder encapsulated in vegetarian capsules (usually 300â500mg per capsule).
- Liquid extract - Alcoholâbased tincture standardized to 5% citral, taken as 10-15drops daily.
- Powdered smoothie mix - Blend 1-2g of freezeâdried powder into morning smoothies or juices.
When selecting a product, look for the following attributes (all of which can be marked up with microdata in a product catalogue):
| Attribute | Recommended Minimum | Why it matters |
|---|---|---|
| Standardized citral content | â„5% | Ensures antiâinflammatory potency |
| Leafâtoâstem ratio | â„80% leaf | Leaves carry most nutrients |
| Organic certification | USDAâOrganic or EUâOrganic | Reduces pesticide residue risk |
For DIY enthusiasts, a simple method is to airâdry fresh stems, grind them into a fine powder, and store in an airtight glass jar away from light. One teaspoon (â2g) can be mixed with a teaspoon of honey and taken before meals for a soothing effect.
Vietnamese coriander vs. other popular herbs
To illustrate why this herb stands out, hereâs a quick sideâbyâside look at its nutrient profile compared with cilantro, parsley, and basil.
| Herb | VitaminC (mg) | VitaminA (”g RAE) | Key antioxidants |
|---|---|---|---|
| Vietnamese coriander | 45 | 200 | Citral, Quercetin |
| Cilantro | 27 | 110 | Luteolin, Kaempferol |
| Parsley | 30 | 150 | Apigenin, VitaminC |
| Basil | 15 | 70 | Eugenol, Rosmarinic acid |
Notice the higher vitaminC and the presence of citral in Vietnamese coriander - a combination that gives it a distinct antiâinflammatory edge.
Potential risks, contraindications, and safety tips
While the herb is generally safe for most adults, a few cautions apply:
- Pregnancy - High doses of citral may stimulate uterine contractions; stick to culinary amounts.
- Bloodâthinning medication - The herbâs coumarinâlike compounds could modestly enhance anticoagulant effects.
- Allergy - Rare, but those allergic to other members of the Polygonaceae family should perform a patch test.
For anyone on medication or with chronic conditions, consulting a healthcare professional before starting a supplement regimen is advisable. This aligns with best practices highlighted by the British Nutrition Foundation.
Integrating Vietnamese coriander into your everyday routine
Here are five practical ideas to make the herb a habit without feeling forced:
- Add a pinch of dried powder to your morning oatmeal - it blends well with fruit and honey.
- Stir a few drops of liquid extract into postâworkout smoothies; the citrusy note masks any bitterness.
- Swap a standard capsule of multivitamin for a Vietnamese coriander capsule on days you need extra digestive support.
- Season grilled fish or chicken with a fresh Vietnamese coriander pesto (leaf, garlic, lime, olive oil).
- Make a refreshing summertime iced tea: steep dried leaves, add a splash of lemon, and chill.
These approaches keep the flavor lively while delivering the herbâs nutrient punch throughout the day.

Frequently Asked Questions
Can I eat Vietnamese coriander raw, or does it need to be cooked?
Both ways work. Raw leaves retain the highest vitaminC content, while light cooking mellows the flavor and can increase the availability of some antioxidants. Many Vietnamese dishes use the herb fresh in salads, soups, and spring rolls.
How much Vietnamese coriander should I take as a supplement each day?
A typical dose ranges from 300mg to 600mg of standardized powder, or 10-15drops of liquid extract. Start at the lower end to assess tolerance, then gradually increase if needed.
Is Vietnamese coriander safe for children?
Small culinary amounts are fine for kids. For supplemental forms, most experts recommend waiting until the child is at least 12years old and consulting a pediatrician first.
Can the herb interact with my bloodâpressure medication?
Because Vietnamese coriander can modestly lower blood pressure, it may have an additive effect with antihypertensive drugs. Monitoring your blood pressure and discussing with your doctor is prudent before adding a highâdose supplement.
Where can I buy highâquality Vietnamese coriander supplements?
Look for reputable brands that list a certified organic source, provide a citral standardization (â„5%), and include thirdâparty lab results. Health food stores in the UK and online marketplaces often carry such products.
This is just another fake health trend pushed by big herb companies. Vietnam doesn't even use this as a supplement, it's just a garnish. Stop selling snake oil to gullible Americans.
I've been adding fresh rau ram to my pho for years and never thought of it as a supplement. But honestly? My digestion has been way better since I started eating it daily. No pills needed. Just good food. đż
The invocation of traditional Southeast Asian pharmacopeia in the context of Western nutraceutical frameworks presents a fascinating epistemological tension. While the biochemical constituents of Persicaria odorata are indeed noteworthy, their reduction to quantifiable metrics risks the erasure of their cultural and ritualistic significance within indigenous healing systems. One must ask: is this herb being utilized, or merely commodified?
Wait so you're telling me this herb can lower blood pressure? đł But my uncle took it and his BP dropped to 80/50 and he passed out. I'm telling you, this is dangerous. People are dying from this stuff and no one's talking about it. đ

Let me guess - this is a CIA psyop. Theyâve been spraying citral-laced mist over urban areas since 2018 to lower blood pressure and make people docile. Look at the timing - right after the FDA approved 5G rollout. The âtraditional useâ? A cover. The âclinical trialsâ? Funded by Big Herb. They want you to believe youâre ânaturalâ while they quietly control your autonomic nervous system. Check the patent filings. Iâve got screenshots.
I think Sanjoyâs comment hits the nail on the head - sometimes the simplest way is the best. Iâve been growing rau ram in my windowsill since last spring. A few leaves in my salad every day, no capsules, no tinctures. My energyâs steadier, and I actually enjoy eating more. Science is great, but real life doesnât need a 12-page breakdown to find what works. đ±
