Liferoot (Senecio aureus)
Although considered poisonous by many authors, I have found the tincture of the fresh aerial parts (flowers, stalks, and lyre-shaped leaves, plus a few basal leaves) of liferoot to be one of the very best remedies for women with extremely painful menses. Doses of 5-10 drops, taken daily between the last days of the flow and ovulation, are generally successful after 4-5 months. More in New Menopausal Years the Wise Woman Way.

Trout lily (Erythronium americana) AKA Adder’s tongue
The mottling of the leaves resembles the pattern on a trout, thus the name. Although lilies whose flowers point down or to the side are generally poisonous, the little trout lily leaves may be eaten, with caution. Like wild lily of the valley, there are hundreds of plants growing on the floor of my woods, but few that actually bloom. Protect this plant.
