Although I never heard of it, it may be a common name for the chamomile or chamomile plant from a syncopation in its scientific name Matricaria recutita. It can also be a repetition or intensification, using the prefix re-, of cuita in its meanings of "manure", "craving" or "very hard work". But surely it is a dictionary error and they are consulting for catalan/recuita ("tempered, annealed").
