I love tea, especially herbal tea. But there oddly seems to be none in this game, considering those would have been the only teas really available in this setting.
Without a teabush I cannot and will not waste clay on tea. But I would make tea if I could make herbal tea.
Especially from berries. Gives a boost lasting half an hour equal to 10X the berries in the recipe (i.e, blackcurrant tea using 3 blackcurrants would give 3 strength for 30 minutes, stacking up to 1.5 hours).
Making rootfill a tea that heals 1 HP every 2 hours on every wound (including stitch patch ones) lasting 4 hours (for a total of 2 HPs in 4 hours) also seems like a good idea.
