What traditional uses of Western Larch were recorded among Native American peoples?

Native American traditions recorded several uses for Western Larch, mainly involving the bark, sap, and plant tops. The Kutenai used an infusion of bark for tuberculosis and gum for cuts and bruises, while the Nez Perce used bark infusions for colds and coughs and chewed the sap for sore throats. The Okanagan-Colville soaked arthritic limbs in a decoction of the plant tops (Hart, 1992; Turner et al., 1980).

How did different groups use Western Larch for respiratory issues?

Nez Perce traditions recorded the use of Western Larch bark infusions for colds and coughs, and chewing the sap for sore throats. The Kutenai also used a bark infusion for tuberculosis. These uses were documented in the early 1990s by Jeff Hart in Montana Native Plants and Early Peoples (Hart, 1992).

Did Western Larch play a role in wound care or skin remedies?

Gum from Western Larch was used by the Kutenai for cuts and bruises. This topical application is one of the few non-respiratory uses recorded and was documented by Jeff Hart in 1992 (Hart, 1992).

Who should grow Western Larch and who should skip it?

Grow Western Larch if you have space for a large conifer and need a tree that gets by on low water. Skip it if you garden on heavy clay that stays wet, or if you want something edible. Renters with only a balcony or anyone looking for a tree for small yards should look elsewhere. Deer pressure is less of an issue, but space is not negotiable.
