The fruits from this palm tree with a high content of fatty acids (oleic, lauric, myristic, linoleic and linolenic acids) are used. They also contain flavonoids and phytosterols (beta-sitosterol) that exert both an antiandrogenic and estrogenic action
It is used for treatment of prostate hyperplasia. Also used, however on a poor scientific basis, for treatment of androgenic alopecia and hirsutism (Murugusundram 2009, Rossi 2012, Wessagowit 2016)..
It has been related to some problems such as hormonal disruption when it was used in girls (Morabito 2015), but mostly without serious side effects (Agbabiaka 2009).
At latest update no published data on excretion into breast milk were found.
No likely risk when topically used, whenever it is not applied on the chest.
A moderate consumption would not represent a risk while breastfeeding. It may be prudent to avoid using it during the neonatal period (within first month after birth) and in cases of prematurity.
Cautions when taking herbal teas:
1. Make sure it is obtained from a reliable source: reportedly, poisonings have occurred due to confusion after using another plant with toxic effects, some others contain heavy metals that may cause poisoning and others may cause food poisoning due to contamination with bacteria or fungi.
2. Do not take it excessively. "Natural" products are not always good in any amount: plants contain active substances from which are made many compounds of our traditional pharmacopoeia that can cause poisoning if consumed in exaggerated quantities or for long periods.
