Healthy foods (Colombo)

Hi

I was wondering if anywhere sold almond milk or rice milk as well as gluten-free bread and gluten free food alternatives? Being on a dairy and gluten free diet in a new country is always a challenge..

Also, I am looking to make my own herbal teas at home. Anyone got any experience of making or know what edible herbs/flowers are grown here that might be nice for drinking?

Thank you!
Best
