O que é
Harpagophytum procumbens DC. ex Meisn. — secondary root tuber (Harpagophyti radix)
Agrupado aqui em Joints, urinary tract and hormones. Posição regulamentar:Monografia de plantas da UE — uso tradicional.
O que a evidência apoia
A indicação registada:Relief of minor joint pain, and of mild digestive complaints such as bloating and loss of appetite.
A southern African plant whose secondary root tubers are dug for the European joint-pain market. The registered indication is deliberately modest — minor joint pain — and that modesty is doing real work: trials of standardised extracts in low back pain and osteoarthritis exist, but they are mostly small, short and of moderate quality, and systematic reviewers have generally called the evidence promising but insufficient. The clinical detail that separates it from the rest of the joint-supplement shelf is its contraindication in peptic ulcer disease: devil's claw increases gastric acid secretion, so monograph texts contraindicate it with active stomach or duodenal ulcers. It is also wild-harvested, and pressure on wild populations in Namibia, Botswana and South Africa has been a long-running concern.
C — Traditional use only Plausible from thirty or more years of use, which is what a traditional-use registration means. No clinical evidence was required and none has settled it.
Para que não é
Inflammatory arthritis, a hot swollen joint, joint pain with fever, or back pain with leg weakness, numbness in the saddle area or loss of bladder control — the last of those is an emergency.
Forma, força e durante quanto tempo
Dried secondary tuber as tea, and standardised dry extracts in tablets, usually standardised to harpagoside content.
Duração.Traditional-use texts direct people to seek advice if joint pain persists beyond a few weeks of use.
Nenhum número em gramas aparece nesta página de propósito. A parte da planta, o solvente de extracção e a razão droga-extracto juntos definem uma preparação, e um número tirado de uma não descreve outra. O raciocínio está no hub; a quantidade que se aplica a si é a impressa na embalagem que segura, e um farmacêutico lê-a consigo.
Efeitos adversos
Digestive upset and diarrhoea are the common ones, alongside headache and dizziness. Allergic reactions occur.
Quem deve evitá-lo
Contraindicated with active stomach or duodenal ulcer. Caution with gallstones. Not in pregnancy; adults only.
Interações com medicamentos
| Medicamento ou substância | O que é descrito |
|---|---|
| Anti-inflammatory painkillers (NSAIDs) | It is often taken to reduce the need for anti-inflammatory painkillers, and the two share a gastric-irritation profile — which is exactly the combination the ulcer contraindication is about. |
| Anticoagulants and antiplatelets (warfarin, DOACs, aspirin, clopidogrel) | Case reports of altered warfarin control exist. With any anticoagulant, tell the prescriber before starting. |
| Diabetes medicines and insulin | Blood-glucose lowering has been reported; monitor if you take glucose-lowering medicines. |
