The best way to find out what plant is what is to take your villager and hover him/her around the island. It will say what they see.

Cactus x 2 + Lotus restores them.
Cactus x 3 makes them healthier.

I don't know if this is listed yet, but the lotus + orchid + orchid is great. It makes the villager feel woozy, but if you put them to their task, they will improve at it! All of my villagers became adept this way...

My fav is Cactus X3, they feel better when eating well.

Good luck

ok I'm a little confused....HOW do I get to make a potion?? I've gathered 3 cactus....and have tried everything to make a potion. Do I need a certain level of something before I can make it?

wheww..nevermind the answer to my question above. Just got it to work. Funny thing was I already did what I just did again, but it wouldn't work before. Oh well, least it worked this time.

Two roses and a cactus makes them fertile so can get more babies

oh and stand someone on the lift when it starts raining to get summat fall off the tree to plant in the soil

2 Cactus plus lotus just blew up and now my scientist has no red in its stats level.... he's dying. Now what? lol

I think

Cactus cactus lotus - renewed health
cactus lotus cactus - blow up.

I keep getting them in the wrong order and the lotus arriving at the table before the last cactus. I thought i got the order right but now i am extra careful!
