Consuming Milkmaid Tea while pregnant

Emma • Mum to Harlen Jane🌷July 6th,’18 & Nolan Stone 🍭June 28,’19

I gave birth to my child in July, and we’re EBF. I am not currently pregnant, but am also not preventing pregnancy so it could happen anytime.

I currently drink a few cups of milkmaid tea per day, but it says not to drink it while pregnant. There’s also like 7 different things in it though.

My question is, which herbs/spices are harmful during pregnancy? So that if I bought the herbs separately and made my own I could leave out the harmful ones and make a safe mix.
