What is gotu kola?
Gotu kola is a plant that grows in wet ground. Its scientific name is Centella asiatica, and in English-language products it's usually sold as Gotu Kola. The skincare ingredient called "cica" comes from this same plant.
Applied to the skin, it's used for wounds and soothing. Taken by mouth, it's mostly used to strengthen blood vessels, especially the veins in your legs. Its key compounds are triterpenes like asiaticoside (the main group of compounds behind gotu kola's effects).
Gotu kola benefits: where it may help
| Benefit | What it does | Strength of evidence |
|---|---|---|
| Leg swelling and circulation | Firms up vein walls to ease leg swelling and tight, achy calves | The most common use, with human studies |
| Capillaries | Lots of research on the tiniest blood vessels too | Plenty of research |
| Wounds and skin | Helps make collagen (the protein that keeps skin firm) and calms inflammation | Mostly experience with topical use |
| Liver enzymes | A study found enzyme levels dropped in adults with high liver enzymes after 12 weeks | About 1 human study |
| Eyes (macula) | Experiments showed less retinal damage | Cell and mouse studies only |
| Nerves and memory | Possible nerve-protective effects have been discussed | Still just a possibility |
For leg swelling, a study of 52 people with weak vein circulation found that swelling and ankle circumference went down, and higher doses had bigger effects. Some people say calf pain eased in about a week.
For the liver, 79 people with high liver enzymes (blood test numbers that rise when the liver is damaged) took it for 12 weeks: ALT dropped by about 20, AST by about 11, and triglycerides went down too.
Who should consider gotu kola
- □ Your calves feel tight and heavy after standing or sitting for a long time
- □ Your legs and ankles swell by evening
- □ Your hands or calves swell easily
- □ You get leg cramps and feel like your circulation is poor
- □ Your wounds heal slowly, or you're concerned about skin firmness
Avoid it, or check with your doctor first, if:
- You have liver problems: there are rare reports of liver enzymes rising.
- You're pregnant or breastfeeding: there's no safety data for taking it by mouth, so avoid it. Topical products are fine.
- You take sleeping pills or sedatives: drowsiness may get worse.
Gotu kola dose and how to take it
| Standard | Daily dose |
|---|---|
| Typical range for most products | 100–500 mg (extract) |
| Amount approved in some countries | 300 mg gotu kola |
| Known upper range | Reportedly used at up to 1,500–2,000 mg |
- Start with a low dose. Studies suggest the effect grows with the dose, but it's best to see how your body handles it first.
- Take it steadily as the label directs. It's known to be relatively safe for long-term use.
- Watch whether your leg discomfort changes within 1–2 weeks.
How to choose gotu kola: 4 things to check on the label
- A standardization % is listed — you want the % of a marker compound (a reference compound used to gauge quality), like "Asiaticoside 10%" or "Triterpenes 10%." If it just says "Gotu Kola 950 mg (aerial parts)," there's no way to know how much active compound is inside.
- Calculate the real amount — if it's 500 mg of extract at 10% triterpenes, the active amount is about 50 mg. Use this number to compare products.
- Leaf-sourced — marker compounds are concentrated in the leaves, so leaf-based raw material has a quality edge.
- DNA verification — herbs can be contaminated with other plants. A mark showing the source plant was DNA-verified (like TRU-ID) makes it more trustworthy.
| What the label says | Verdict |
|---|---|
| Extract ___ mg (asiaticoside ___%) | Good — you can calculate the active amount |
| Powder + standardized extract together | Good — total active compounds may be higher |
| Only "Gotu Kola herb ___ mg" | Fair — you can't tell the real active amount |
Finally, choose a trustworthy company with a reasonable price.
What to pair it with: Pycnogenol and omega-3
- Pycnogenol (pine bark extract): the most common partner for gotu kola for blood vessels and leg circulation. Some circulation products combine both in one capsule.
- Omega-3: helps blood flow smoothly, and some say it works synergistically with gotu kola for circulation.
Gotu kola side effects and precautions
- Stomach upset and allergies: rarely, it may upset your stomach or cause an allergic reaction.
- Liver enzymes: some studies show it lowered liver enzymes, but there are also reports of liver enzymes rising. If you have liver problems, don't take it, and if you take it long term, check your liver enzymes at checkups.
- Pregnancy and breastfeeding: there's no data on taking it by mouth, so avoid it. Topical products are fine.
- Sleeping pills and sedatives: the sedative effect may get stronger. If you take them together, talk to your doctor.
If swelling suddenly gets much worse in just one leg, or the leg turns red, hot and painful, don't rely on a supplement — get medical care right away.
Medications and conditions to watch
- Check Sleeping pills and sedatives — Sedation and drowsiness may get stronger — talk to your doctor if you take them together
- Check Liver disease treatment — Rare reports of rising liver enzymes — talk to your doctor before taking it
Combinations
Works well with: Pycnogenol, Omega-3
