The original Catambra is always sold together with its brand and a label which can't be ripped off.

Catambra is the only plant able to keep mosquitoes away in a natural way, ensuring you and your family an effective protection. This plant belongs to the Bignognacea's family, coming from northern America and, thanks to the high quantity of Catalpol, a natural substance, it has got a repellent action against mosquitoes.

Catambra is a surprising plant which doesn’t require any special care and it easily adapts. It can grow in soil or pot and can be put in the sun or in the shade, it doesn’t smell; it doesn’t flourish and it doesn’t grow in height; only its stem and foliage swell. Its repellent action extends to an area that is twice its foliage, so it is not necessary to prune it several times. More foliage means more protection.

Laboratory analysis carried out from the Experimental Centre for Floriculture confirm that Catambra contains a quantity of Catalpole that is four times superior to any other specimen and it is particularly effective to keep mosquitoes away, including tiger mosquitoes that have been infesting Italy for some years.
