Yes, raspberry leaf tea will not trigger labor, if that's what you are going for then tulsi (holy basil) potentially can do that. It stimulates the uterus and circulates blood flow which can trigger labor, there are an endless number of benefits to drinking tulsi but how safe it is for pregnant women are unknown as are most ayuervedic herbs, the only information known of tulsi in relation to pregnant women are cultures/tribes that traditionally give it to women at the end of their pregnancy. My knowledge is based on my understanding of what tulsi does to the body and from this I would say I do not recommend regularly drinking tulsi before reaching full term. Also when it comes to inducing labor naturally these methods will not work unless your baby is ready.
Red raspberry leaf tea isn't supposed to put u in labor, it's supposed to help tone ur uterus for birth making is easier process for labor and birth. I started drinking it 3 days ago.
