Thanks! :)
I didn't add an inn in the starting village as it's the home town of the protagonists, so there's no need for them to use it (of course not the entire village is included on the starting map, so there is an inn somewhere, you just can't access it).
As for the healing items, you're meant to craft them yourself. Explore the village, especially Camellia's house and you'll find quite a few recipes and empty flasks. If you "use" the recipes in your item menu, they will be added to your crafting menu, and you'll be able to access the ingredients. You can fill the empty flasks at wells and combine them with herbs... you'll get the flasks back after you use the potions, so you don't need to get new ones every time.
The first healing item is called Eidelweiss Potion, its recipe is on the first map after the village.
Hopefully that answered your question. Good luck, hope you enjoy the rest of the game! :D
