Edible Uses

Edible Parts: Seed Edible Uses: Condiment Tea Western mugwort leaves provide a pungent seasoning but are unpleasantly bitter. Seeds were historically used, but they are limited in terms of safety and palatability. Overall, a survival food rather than a regular edible [2-3]. Leaves and flowering heads are used as a flavouring or garnish for sauces, gravies, etc[183]. A herb tea is made from the leaves and flowering heads[183]. Seed[105, 161, 177, 183]. No further details are given, but the seed is very small and fiddly to use.

The wash was also applied to eczema and as an underarm deodorant[257]. A poultice of the leaves can be applied to spider bites, blisters and burst boils[257].
