One ingredient for the cat curing allergy potion is a cup of hot camomile tea.

Do you have a camomile flower, already?

So, you would need to heat some water and the infuse the flower there, right?

Go to the vegan daycare. There's a pot of cold water and coals beneath it.

I think you have to light the coals.

Good. Now, infuse the camomile flower in the water.

Grind the flower, first. There's some grinding equipment nearby.

There is a mortar in the shack. Use the camomile flower on the mortar to grind it.

Use the grounded camomile on the hot water to make the tea. You can put the tea into the mug you have with you.
