Groen Amara is a traditional Afrikaans bitter tonic — a “boererate” remedy taken by the spoonful for indigestion, poor appetite, bloating and general sluggishness. It has been sold in South Africa for generations. It does not appear on the medicine price registry, and what is in your bottle depends on which one you have.
What is Groen Amara?
No product called Groen Amara appears on the South African Medicine Price Registry, which lists SAHPRA-registered medicines and their prices. This page therefore does not assert what is in your bottle — read the label.
“Amara” is the pharmaceutical term for bitters — from the Latin amarus, bitter. Bitter tonics are one of the oldest categories of remedy in European and South African pharmacy, and “groen” simply means green in Afrikaans, distinguishing it from other Amara preparations.
Traditional bitters of this kind are alcoholic or aqueous extracts of bitter herbs. The plants historically used include gentian, wormwood, aloe, rhubarb root, angelica, centaury and quassia, often with aromatic additions such as anise, cardamom or peppermint. Formulations differ between manufacturers and have changed over time, which is exactly why the label matters more than the name.
The traditional theory behind bitters is not baseless. Bitter compounds on the tongue trigger a reflex that increases saliva, stomach acid, bile and digestive enzyme secretion, and stimulates gut motility. The mechanism is real and measurable. What is much weaker is the evidence that this translates into meaningful benefit for any specific condition — most of the research is small, old, or from laboratory work rather than clinical trials.
Two practical cautions follow from the ingredients.
Many bitter tonics contain a substantial amount of alcohol — historically 20 per cent or more — because alcohol extracts the bitter compounds efficiently. Check the label. This matters if you are pregnant, in recovery, driving, giving it to a child, or taking metronidazole or other medicines that react with alcohol.
Some traditional bitters contain anthraquinone laxatives — aloe, rhubarb root, senna, cascara. These stimulate the bowel, and prolonged use causes dependence, cramping and salt disturbance. A tonic that reliably produces a bowel movement is working as a laxative, whatever else it is doing.
What is Groen Amara commonly used for?
Traditionally taken for:
- Indigestion, fullness and bloating after eating.
- Poor appetite, particularly during recovery from illness — the classic bitters indication.
- Sluggish digestion and a feeling of heaviness.
- Constipation, where the preparation contains a laxative herb.
- Wind and mild abdominal discomfort.
- General malaise and “cleansing”, in the traditional framing.
- Nausea, in some traditional use.
What the evidence actually supports. Bitters plausibly stimulate appetite and digestive secretions — the strongest of the traditional claims, and the one with an understood mechanism. Claims about detoxifying, purifying the blood, or treating disease are not supported. The liver and kidneys handle detoxification continuously and do not need help from a tonic.
Timing follows from the mechanism. Bitters are traditionally taken before a meal, since the point is to prime digestion. Taken after eating, the rationale largely disappears.
Persistent indigestion deserves better than a tonic. Regular symptoms for more than a couple of weeks warrant proper assessment — reflux, H. pylori infection, gallstones and ulcers are all common, treatable, and better identified than managed indefinitely with bitters.
How Groen Amara fits into this medicine category
It is a traditional remedy rather than a registered medicine, which is the most important thing to know about where it sits:
| Type | Examples | Regulation |
|---|---|---|
| Traditional bitters | Groen Amara, Lewensessens, Duiwelsdrek | Health supplement; light regulation |
| Antacids | Gaviscon, Rennies | Registered medicines |
| Acid reducers | Famotidine, omeprazole, pantoprazole | Registered; prescription or pharmacy |
| Antispasmodics | Hyoscine | Registered |
| Laxatives | Macrogol, lactulose, senna | Registered |
| Digestive enzymes | Pancreatin | Registered; for specific conditions |
“Traditional” does not mean inert, and it does not mean safe. A preparation containing alcohol and stimulant laxative herbs has real effects and real interactions — it is simply less studied and less tightly regulated than a registered medicine.

What to check before using Groen Amara
Read the label, and check for:
- The alcohol content. Often significant in traditional bitters.
- Laxative herbs — aloe, rhubarb root, senna, cascara, frangula.
- Wormwood, which contains thujone and is not for prolonged use or for anyone with epilepsy.
- Sugar content, if you have diabetes.
- A SAHPRA registration number, whose absence confirms it is a supplement rather than a registered medicine.
Speak to a pharmacist or doctor before taking it if you:
- Are pregnant or breastfeeding. Bitter and laxative herbs are traditionally avoided in pregnancy, and the alcohol is a separate concern.
- Are giving it to a child. Alcohol-containing tonics are not suitable for children.
- Have epilepsy — relevant if it contains wormwood.
- Have inflammatory bowel disease, a bowel obstruction, or undiagnosed abdominal pain. Stimulant laxatives are dangerous in these.
- Have stomach ulcers or gastritis, where increased acid secretion may not help.
- Have liver disease or are in recovery from alcohol dependence.
- Take metronidazole, or any medicine that reacts with alcohol.
- Take warfarin, digoxin, diuretics, diabetes medicines, or heart medicines. Stimulant laxatives lower potassium, which matters with digoxin and diuretics.
- Have kidney disease.
Practical points:
- Take it before meals, as traditionally intended.
- Use it occasionally, not daily and indefinitely — particularly if it contains a laxative herb.
- Do not use it to push on through persistent symptoms.
- Tell your doctor and pharmacist you take it, alongside everything else. Herbal preparations interact with medicines, and they cannot check for it if they do not know.
Possible cautions and when to ask a pharmacist or doctor
Common effects are usually mild: a strong bitter taste, nausea, abdominal cramping, and loose stools where a laxative herb is present.
Seek prompt advice for:
- Persistent diarrhoea or cramping.
- Muscle weakness, palpitations or unusual tiredness — possible low potassium from prolonged laxative use.
- A rash or itching.
- Yellowing of the skin or eyes, or dark urine — some herbal preparations cause liver injury.
- Worsening indigestion or new abdominal pain.
Get emergency help for severe abdominal pain, vomiting blood, black tarry stools, or swelling of the face, lips or tongue with difficulty breathing.
See a doctor rather than continuing to self-treat if you have:
- Difficulty or pain swallowing.
- Unintentional weight loss.
- Persistent vomiting, or vomiting blood.
- Black tarry stools, or blood in the stool.
- Anaemia or unexplained tiredness.
- New indigestion over the age of 45 to 50.
- A persistent change in bowel habit.
- Pain that wakes you at night, or pain after eating that is becoming predictable.
That list matters. Indigestion is usually benign, but it is also how ulcers, gallstones and — less often — stomach and oesophageal cancer present. A traditional tonic can settle the symptom while something that needs finding continues underneath, and the delay is the harm, not the tonic itself.

Frequently asked questions
What is Groen Amara used for? Traditionally for indigestion, bloating, poor appetite and sluggish digestion. It is a bitter herbal tonic — “amara” means bitters — and is a supplement rather than a registered medicine.
Is it a registered medicine? No. It does not appear on the South African Medicine Price Registry. Read your label for the ingredients and check for a SAHPRA number.
Does it work? Bitter compounds do measurably increase saliva, stomach acid, bile and digestive enzyme secretion, so the appetite and digestion claims have a real mechanism. Claims about detoxifying or purifying the blood do not.
When should I take it? Before meals. The point is to prime digestion, so taking it afterwards largely defeats the purpose.
Does it contain alcohol? Traditional bitters often contain a substantial amount — check your label. It matters in pregnancy, in recovery, for children, and with metronidazole.
Is it a laxative? Some formulations contain aloe, rhubarb root or senna, which are stimulant laxatives. If it reliably produces a bowel movement, that is what is happening.
Can I take it every day? Occasional use is the traditional pattern. Daily indefinite use is not advisable, particularly with a laxative herb.
Can children take it? Not if it contains alcohol, which most traditional bitters do. Ask a pharmacist.
