  1. The bay leaf looks like roseamary leaf and your description got me confused, thinking that you were referring to rosemary leaf.

    How do I differentiate between the two when I see them in the market?

    1. Thank you, Beybe. Bay leaf is actually different from rosemary plant. However, rosemary is beneficial, health wise.
