Raspberry tea is known in Israel as petel tea. It is used especially in pregnancy- against morning sickness[nausea].
Also, excellent for diarrhoea
It is considered as “good for everything” during pregnancy , also used for threatened miscarriage.
Does it help for labor? It was found that the herb did not help especially for the first stage of labor (contractions, dilation).
But it did for the second stage [fewer complications, easier birth]
