At latest update, relevant published data on excretion into breast milk were not found.

Because its estrogenic effect it should not be consumed during pregnancy and breastfeeding.

Caravanina which is one of the components, is toxic if continuously used. Pancytopenia, Hemolytic anemia and Lupus Erythematosus have been described as induced by frequent consumption of germinated-seeds or tablets of alfalfa.

Cautious measures before consumption of herbal infusions should include:

1. Make sure that the source is reliable: occurrance of intoxication cases after mistakenly use of a toxic plant, poisoning by consumption of heavy metal containing substances or contaminated food by bacterial or fungal toxins.

2. Avoid excessive use. The “natural products” are not harmless at whatever dosage: the plants contain active substances that have been the source of our common pharmaceutical drugs. They may be a cause of poisoning if consumed in high quantity or for a long time.
