This is a tree of variable size, which, according to growing and climatic conditions, can vary from 1.5 to 5 m in height. The fruits are globose yellow or red berries, tasty, with a diameter of about 1.5 cm. The plant is found in South and Southeast Brazil, Uruguay and Argentina.
HOW A CIDR WORKS. CIDRs are coated with progesterone. Progesterone is a naturally produced steroid hormone by the corpus luteum of mammalian ovaries. In vivo, progestrone functions to maintain pregnancy. Progesterone provides a potent suppression of estrus, making it important for estrus synchronization in herds of animals.
As opposed to OCs, which use synthetic estrogens that affect the cytochrome P450 oxidase system, some formulations of HRT contain conjugated estrogens that do not affect that system. The levels of hormones in HRT preparations are much lower than those in OCs. Progesterone on its own has been thought to be associated with dysphoric moods; continuous combined therapy with estrogen and progesterone may counteract this effect of progesterone.
