Corn / Mais
Seabuckthorn / Sanddorn
Birch polypore / Birkenporling
Rosehip / Hagebutte
Already used Seabuckthorn and Rosehip for tea!
Both are great to get a lot of Vitamin C & D while there ain't much sun! ;)
Birch polypore is also a very useful medicinal mushroom! Oetzi had it with him. I'm just not sure if mine are too old to use for tea? (I actually use very old ones to sharpen my knife, cuz they become very hard and that works too ;))
