Herbal Tea for baby?

Is anyone else ok with giving their baby some fresh herbal tea with their bottle? My LO is very gassy, fussy, and colicky. He wasn't really sleeping well at night (Waking every 1.5-2 hours) and he naps for only up to 30 min or so and has to be in my arms. I warmed up his water before putting in the formula and then brewed some chamomile tea in there for about 1 min, then added the formula. Took baby a lavender bath, gave him his bottle and for the 1st time in 8 weeks he slept for 5 hours straight, then got up to eat and be changed and then slept again for another 4 hours before he was up. I also give him mint tea on occasion to soothe his tummy. He loves the taste and it helps him out. I don't put sugar or anything extra and I don't give him excess water so I see nothing wrong with it. Anyone else agree or feel like it benefits their little ones?
