Hi Kristina,
Welcome to Etsy!
I think you need more descriptions on some of the products. Some questions I think buyers would have are is it scent free, what does it smell like, how do I take the digestive one - mix in a drink?
The photography is good as far as display goes but the images are low resolution. This could be a problem if you took them with a low resolution camera or if you pulled the pictures from a memory card instead of downloading them to your computer and then uploading them.
You get 13 tags so be sure to use ALL of them! :) Yes, start pinning them to Pinterest and I see you have a Facebook page with a good bit of followers, now you just need to link it to your Etsy page.
And I agree with the others you need a banner! I'm a graphic designer if you would like one created let me know.
Good luck on your new business venture!
Summer
