Galax I only know of one variety of Galax, Galax urceolata. This plant was very important to the people of the Appalachian Mountains where I live, but was not much used medicinally. Galax was gathered to sell to the florist industry and a green decoration. However, Plants for A Future states, “The plant is used for healing all kinds of wounds and cuts. An infusion of the root is used to treat kidney problems.”
We have some native Aussie Gaultheria down south (Tas & Vic). Berries edible but bitter.
Interesting. Ours don't have much flavor.
