A passage from Medicinal Plants of the Western Mountain States:

Not significantly antispasmodic, Fireweed combines well with most Mints if a degree of smooth muscle sedation is needed (spastic diarrhea for instance). Alone or combined with equal portions of Canadian fleabane, use it as a daily tea to diminish tissue inflammation associated with ulcerative colitis (crones disease). With regular use, area sensitivity and disarray will reduce, as will ulcerative factors.
