The over 50 women + the fertile potion do not make them able to have children, this has been tried.

I, too, tried at least a dozen times, without success. She goes into the hut, but never conceives or has a baby.

You've just helped me out as well, thanks. I made 1 and it blew up, so I put her on farming as she only had half health bar.

There is no potion for the chief to make food, once every 24 hours your chief (on level 1 leadership) will make food, there is no "set" amount, the first time there was about 250 food, the 2nd time there was about 325 food made. If you have level 2 leadership, once every 24 hours your kids can get educated by the chief which makes your kids smarter to that by the time they get to 14 and start to help out, they can have higher levels and get to master quicker, which is one of the awards if they get to master before 18.

is there a guide for all the potion recipes as of yet ????

Yes, they are in the VV3 Guides section of the forums.

Here are some interesting ones I got:

a. 3 tiger lillies: "Oh what a fun potion!" The adult villager started acting like kids, ran around looking for mushrooms. (I should've tried it on a kid)

b. Lotus, tiger lily, cactus: causes hunger

c. Berry, cactus, cactus: villager became freezing cold!

d. Rose, tiger lily, lotus: villager became woozy.
I'm editing this because I forgot a particularly funny one:
e. 3 roses = "he feels romantic!"

I am also getting the villagers sick with the speed potion.
One of my villagers found a vial with lotus+lotus+cactus for a more powerful healing potion.

*****Spoiler*****

The lotus is the light purple plant by the bath, the pitcher plant is the red one behind the Alchemy labe. The Rose red and is in the orchard against the rocks and the Tiger Lily is on the path to the door it's orange, the Orchid is dark purple and is below the orchard when you hover over them it tells you the name of the plant.

I do. It's catus lotus lotus
