Very High Risk
A parasitic fungus from the ear of some cereals, particularly rye, which since ancient times has caused epidemics of a serious disease, ergotism (Florea 2017, Belser 2013, Lee 2009).
It has a complex composition, highlighting the ergoline alkaloids: lysergic acid amides such as ergometrine and ergopeptines such as ergotamine and ergotoxine (Florea 2017, Hulvová 2013) that act on adrenergic, dopaminergic and serotonergic receptors.
Since the last update, we have not found published data on its excretion in breast milk.
Ergot alkaloids have oxytocic, vasoconstrictive and lactation-inhibiting effects by inhibiting prolactin, among many others (Florea 2017, Hulvová 2013, Lee 2010, Lee 2009).
Indications from the German Ministry of Health’s Commission E: none.
Due to its serious adverse reactions and toxicity, natural alkaloids are not used in therapy, and there are recommendations for their withdrawal from sale (EMA 2014).
Withdrawal or restricted from the market in Spain (MSC 2004).
At present, semisynthetic derivatives such as methylergometrine, dihydroergotamine, dihydroergocristine, bromocriptine and lisuride are used, among others.
We do not have alternatives for Ergot of the rye.
