Devil's Claw: Benefits, Uses & Dosage – An Honest Guide
Devil's claw (Harpagophytum procumbens) is one of the most-searched plants when it comes to joints and mobility – and one of the most misunderstood. Cream or drops? Does it actually work? And why are so many products made for horses? Here is the honest guide from our family drugstore: what tradition says, what research says, and how to use it properly.
- The root has been used for generations in herbal tradition for the wellbeing of joints, muscles and tendons.
- In Europe, medicinal preparations of devil's claw root are recognised as “traditional herbal medicinal products” for mild joint discomfort. Studies on extracts show interesting but mixed results.
- Tradition and research almost always concern the internal use of the root – not creams.
- It is not a quick fix: traditionally used in cycles of 6–12 weeks, together with exercise.
What kind of plant is devil's claw?
The name comes from the small hooks on its fruit, which catch in animals' fur – it is also known as the grapple plant. It grows in the dry regions of southern Africa, especially the Kalahari. The parts used are the tuberous secondary roots: that is where harpagoside, the characteristic bitter compound, is concentrated. The San and Khoi peoples have used them for centuries.
What the research says – honestly
The European Medicines Agency (EMA) recognises pharmaceutical preparations of devil's claw root as “traditional herbal medicinal products” for the relief of mild joint discomfort and mild digestive complaints – a status based on long-standing traditional use, not on full clinical proof. Clinical studies on root extracts show promising but inconsistent results: some point to benefits for back and joints, others find no significant differences. Study quality, dosage and extract type vary widely.
Our druggist's reading: a plant with a serious tradition and interesting signals from research – not a substitute for medical care. For persistent or severe pain, the first step is always your doctor.
Cream or drops? The difference nobody explains
Half of all online searches are about devil's claw creams and ointments. What matters: tradition and studies relate almost exclusively to the internal use of the root. Creams are cosmetic massage products – pleasant, but with little in common with the traditional use of the plant. If you are looking for “the cream”, you are usually looking for the effect of the root – and that comes via drops, capsules or tea.
How to use it: forms and dosage
- 1:1 fluid extract – the most concentrated form: the plant-to-extract ratio is one to one. Typical dosage: 10 drops in a little water, twice a day, after meals.
- Mother tincture – more diluted (usually 1:10): you need far more drops for the same amount of plant.
- Dry extract capsules – convenient and without the bitter taste; though the bitterness is part of the traditional digestive action.
- Tea – the mildest form: the root is woody and needs long steeping.
The same rule applies to all forms: cycles of 6–12 weeks, ideally combined with regular exercise. This is not a “results in three days” plant.
For humans or for horses?
A more common question than you might think: devil's claw is widespread in products for horses and dogs, and online searches often surface the veterinary products first. The answer is simple: the plant is the same, the products are not. Supplements for human use – like our fluid extract – are formulated and dosed for people. If you are searching for “devil's claw for humans”, a fluid extract in drops is the classic form.
Safety: who should take care
- Gallstones: the bitter compounds stimulate bile flow – consult your doctor before use if you have gallstones.
- Pregnancy and breastfeeding: always check with your doctor first.
- Sensitive stomach: in case of gastritis or ulcers, talk to your doctor – bitters stimulate gastric juices.
- Medication: if you take blood thinners or other medicines, inform your doctor.

Frequently asked questions
What is devil's claw good for?
It is traditionally used for the wellbeing of joints, muscles and tendons and to support mobility – especially after physical effort or with advancing age. Tradition also attributes a bitter-digestive role to it.
How quickly do you notice anything?
Not overnight: tradition calls for cycles of 6–12 weeks of regular use, ideally with exercise. If you expect an instant effect, you will be disappointed.
Cream or drops – which is better?
It depends what you are after: creams are cosmetics for massage, while tradition and studies concern the internal use of the root – so drops, capsules or tea.
Is devil's claw suitable for humans?
Yes. The plant is also known from horse and dog products, but supplements for human use are formulated and dosed for people. Our fluid extract is a product for humans.
Who should not take it?
With gallstones, gastritis or ulcers, during pregnancy or breastfeeding, or if you take medication – always consult your doctor first.
Fluid extract, mother tincture or capsules?
The 1:1 fluid extract is the most concentrated liquid form (one kilo of root per litre), the mother tincture is more diluted, capsules avoid the bitter taste – which, however, is part of the traditional action.
