For centuries the Navajos, along with other Native tribes, have brewed a hot drink from the plant, Thelesperma Megapotamicum. Greenthread, as it is more commonly known, is found growing from Arizona to Montana at or above the 4,000 foot level. T. Megapotamicum is a drought tolerant perennial that sends out a long tap root that increases its ability to soak up moister and survive the harsh climates of the West. Unless the winter has been unusually cold and dry, the plant will regenerate itself in the spring. Harvesting usually takes place from early June to late August.
According to lab analysis that we had completed, Navajo tea does contain the flavonoid, luteolin. Luteolin has many qualities including an anti-inflammatory and anti-oxidant. My Grandmother would give us the tea to drink to calm an upset stomach or when a cold was coming on. It has also been used to alleviate pain from a toothache. For me, I just enjoy the taste.
