Devil’s Claw: The Natural Anti-Inflammatory You Should Know About

The devil’s claw, also known as harpagophytum, is a plant traditionally used to support joint health, mild musculoskeletal discomfort, and digestive well-being. Its root contains bioactive compounds, particularly harpagosides, which have attracted interest due to their potential role in modulating inflammation and promoting joint comfort.

In this article, we review what harpagophytum is, its main active compounds, how it is commonly used, what the available evidence suggests, and the precautions that should be considered before incorporating it into your routine.

What is Harpagophytum or Devil’s Claw?

Harpagophytum, whose scientific name is Harpagophytum procumbens, is a herbaceous plant native to southern Africa, particularly regions near the Kalahari Desert.

Its common name, “devil’s claw,” comes from the shape of its fruits, which feature hooked appendages. However, the part traditionally used for herbal purposes is not the fruit, but rather the secondary tuberous roots, where its primary active compounds are concentrated.

Active compounds of harpagophytum

The composition of harpagophytum is complex, and its activity does not depend on a single compound. Among its most notable constituents are:

When choosing a supplement, it is important to check whether it contains powdered root or a standardized dry extract, as the concentration of active compounds can vary considerably.

Properties of Harpagophytum

Support for joint well-being

Harpagophytum has traditionally been used to promote joint comfort and relieve mild joint discomfort. The European Medicines Agency recognizes its traditional use for the relief of minor joint pain, based on its long-standing use in herbal medicine.

Muscle and lower back comfort

Some clinical studies have evaluated Harpagophytum procumbens preparations in cases of non-specific lower back pain. Although the findings are promising, the available evidence should be interpreted with caution and does not replace medical assessment in cases of persistent, severe, or disabling pain.

Antioxidant activity

Harpagophytum contains plant compounds with antioxidant properties that may help protect cells against oxidative stress. This effect contributes to the plant’s broader interest within the context of musculoskeletal health.

Traditional digestive support

Due to its content of bitter compounds, harpagophytum has also traditionally been used to support digestion and stimulate appetite during temporary periods of reduced appetite.

Potential Benefits of Harpagophytum

The most well-known use of harpagophytum is related to joint health and comfort. It may be a supportive option for individuals seeking to care for their joints, particularly when stiffness or mild movement-related discomfort is present.

Osteoarthritis and joint wear

Some clinical trials have investigated the use of harpagophytum extracts in individuals with osteoarthritis. The findings suggest a possible improvement in pain and mobility in certain cases, although more high-quality research is needed to confirm the extent of these effects and compare them adequately with other options.

Non-specific lower back pain

Clinical reviews have evaluated harpagophytum for non-specific lower back pain. Some standardized preparations have shown short-term benefits compared with placebo, although the quality of evidence is considered moderate at best.

Recovery support for active individuals

For physically active individuals, harpagophytum may be of interest as part of a comprehensive recovery strategy that includes rest, proper nutrition, hydration, and effective training planning.

How Does Harpagophytum Work?

The mechanisms of action of harpagophytum are not yet fully understood. Research suggests that its extracts may modulate various pathways involved in inflammation, including mediators such as pro-inflammatory cytokines and enzymes associated with the inflammatory response.

However, it is important to avoid oversimplifying its effects as if it worked in the same way as an anti-inflammatory drug. Harpagophytum is a plant containing multiple compounds, and its effects appear to depend on the interaction of several mechanisms.

How Long Does It Take to Notice the Effects?

Harpagophytum does not usually act as an immediate pain reliever. In studies and traditional use, its potential benefits are generally observed after continuous use for several weeks. As a general guideline, some people may begin to notice changes within 2 to 4 weeks, although individual responses may vary.

How to Take Harpagophytum

Capsules or Tablets

Capsules and tablets are the most commonly used forms due to their convenience and dosage accuracy. They make it easier to know the exact amount being consumed, especially when standardized dry extracts containing defined levels of harpagosides are used.

Liquid Extracts

Liquid extracts or tinctures allow for flexible dosing, although they tend to have a bitter taste. Some products may contain alcohol and therefore may not be suitable for everyone.

Infusions or Decoctions

Harpagophytum root can also be prepared as an infusion or decoction. This is a traditional method of consumption, although it has one drawback: it is more difficult to determine the exact amount of active compounds being consumed.

Suggested Dosage

The appropriate dosage depends on the type of preparation, extract concentration, and harpagoside content. In dietary supplements, daily doses of dry extract typically range from 400–800 mg per day, although the manufacturer’s instructions or the advice of a healthcare professional should always be followed.

As a quality reference, the European Pharmacopoeia includes harpagophytum dry extracts with a minimum harpagoside content. Therefore, when comparing products, it is advisable to review both the total amount of extract and its degree of standardization.

Extract Quality: What Should You Check?

Not all harpagophytum products are the same. To assess their quality, it is worth considering the following factors:

A standardized extract provides greater control over the amount of active compounds consumed than a powdered root product without a declared concentration.

Harpagophytum vs Other Natural Anti-Inflammatory Ingredients

Can They Be Combined?

Some supplements combine ingredients such as harpagophytum, turmeric, ginger, collagen, glucosamine, or chondroitin. These combinations may make sense as part of a comprehensive joint care strategy, although dosage, digestive tolerance, and potential interactions should always be considered.

Side Effects of Harpagophytum

Harpagophytum is generally well tolerated when used at the recommended doses, but it may cause adverse effects in some people. The most common side effects include:

• Digestive discomfort.
• Heartburn or a sensation of gastric irritation.
• Mild nausea.
• Occasional diarrhea.

If any unexpected reaction occurs, it is recommended to stop taking it and consult a healthcare professional.

Contraindications and Precautions

• Pregnancy and breastfeeding: Harpagophytum is not recommended during pregnancy or breastfeeding unless expressly advised by a healthcare professional, due to insufficient safety data.
• Gastrointestinal problems: People with peptic ulcers, active gastritis, significant gastroesophageal reflux, or other relevant digestive disorders should consult a healthcare professional before taking harpagophytum, as its bitter compounds may increase gastric secretion.
• Gallstones or gallbladder problems: Due to its possible effect on bile secretion, people with gallstones, bile duct obstruction, or gallbladder disease should avoid its use unless recommended by a professional.

Before taking harpagophytum, it is advisable to consult a healthcare professional if using medications such as:

• Anticoagulants or antiplatelet drugs: due to a possible increased risk of bleeding.
• Antidiabetic medications: due to a possible influence on blood glucose control.
• Antihypertensive or cardiovascular medications: as a precaution in people with pre-existing conditions.
• Anti-inflammatory drugs or pain relievers used chronically: to avoid duplications or unwanted interactions.
