Raspberry leaf tea....

Chloe 💖
I'm thinking of getting some to start drinking after 37 weeks to help prep my cervix, I've heard it can help soften it ready for labour. I have a few questions though..
1. How often are you supposed to drink it for it to have any effect?
2. When to start drinking it? (My guess is 37 weeks as I'll be 'full term'..?)
3. Is it safe?
Thanks in advance! 🤰🏽😊
