If you are talking about natural colour, then I would recommend the ones from Lancome- awesome range of colours and they taste good too!
If you are talking about naturally made- I can't help you, but suggest that you might want to try making your own.
I like the ones I make myself with Beeswax, Shea, Cocoa Butter, Jojoba, Coconut oil and flavoring! It's wack to spend $5 on a tiny tube or pot when I can make a big batch of it so cheap. Most ingredients are available at health food or bulk food stores like Whole Foods etc.
I actually prefer chemicalized lip glosses,lol. Lancome has the best lip glosses! It is extra shiny, pretty color and just looks good on my full lips.
I tried Natural lip glosses, especially the mineral ones; they feel tacky on my lips. Only ONE I liked was Burt Bees in strawberry, it smells so good and makes my lips soft. I would apply that before I went to bed. It has no color though.
