Caralluma Fimbriata

An Indian edible cactus traditionally used to blunt hunger during long journeys. Trials show a small effect on waist circumference but generally no significant weight loss.

Evidence last reviewed: August 2026

What the science says

  • Body weight Limited evidence

    A systematic review and meta-analysis of clinical trials found no statistically significant reduction in body weight or BMI with Caralluma fimbriata. This is the main claim shoppers buy it for, and it is not supported.

  • Waist circumference Limited evidence

    The same meta-analysis found a small significant reduction in waist circumference. An early randomized trial in Indian adults similarly found reduced waist circumference and some appetite suppression without weight change.

  • Appetite control Limited evidence

    A randomized controlled trial in overweight adults tested an orally dosed extract on appetite control and body composition, with modest and inconsistent results. Trials are small, short and use different extracts.

Dosage & safety

Studied doseTrials used 500–1,000 mg/day of standardised extract, usually split before meals, for 4–12 weeks.
SafetyGastrointestinal complaints (constipation, flatulence, stomach discomfort) and rash are the reported side effects. It has been used as food in India, but supplement extracts are more concentrated. Avoid in pregnancy and breastfeeding for lack of data; a case of hepatotoxicity has been reported with a Caralluma-containing product, so stop if jaundice or dark urine appears.
