What is it?
Camu-camu has not been shown to prevent or treat cancer in humans.
Camu-camu is a small plant that grows in South America. Laboratory studies and a small study in humans have shown that the fruits have antioxidant and anti-inflammatory properties. More research is needed. Because camu-camu has high amounts of vitamin C, it may interfere with certain chemotherapy drugs.

For Healthcare Professionals
Scientific Name
Clinical Summary
Camu-camu is a shrub native to the Amazon region of South America. Due to its sour taste, it is not generally consumed as food. However because of the fruit’s high vitamin C content, camu-camu is marketed as a dietary supplement with superfruit and immune boosting properties, and as having benefit for various conditions including diabetes and cancer.
Camu-camu fruits showed antioxidant and anti-inflammatory effects (5) (6) (7) with pharmacological activity exhibited by the leaves as well (4). In murine models, camu-camu fruits showed protective prebiotic effects against obesity (8); and shifted gut microbial composition that translated into antitumor activity along with a stronger anti-PD-1 response (9). A study is underway to determine if camu-camu can modulate gut microbiota in AIDS patients on antiretroviral therapy (10).
Due to its high vitamin C content, camu-camu may interfere with certain chemotherapy drugs. However, vitamin C content in frozen camu-camu pulp was shown to decrease progressively (1).
Purported Uses and Benefits
- Cancer
- Immune system
- Atherosclerosis
- Arthritis
Mechanism of Action
The compounds isolated from the leaves of camu-camu, ellagic acid, 4-O-methylellagic acid and 4-(alpha-rhamnopyranosyl) ellagic acid, were found to exhibit noncompetitive inhibition of aldose-reductase, a possible target for diabetes mellitus (4). Camu-camu juice decreases inflammatory and oxidative stress markers such as 8-hydroxy-deoxyguanosine, total reactive oxygen species, C reactive protein, IL-6, and IL-8 in smokers (5).
Herb-Drug Interactions
- Camu-camu has a high amount of Vitamin C which is an antioxidant. It may interact with certain chemotherapy drugs that rely on the generation of free radicals for their cytotoxic effects.
