Erechthites. Erechthites hieracifolia (L.) Raf. Fire-weed.—An annual indigenous composite plant, growing in moist woods and recent clearings, and having a rank, somewhat aromatic odor. Its taste is bitterish, slightly acrid, and disagreeable. It yields its virtues to water. It has been especially recommended in dysentery. It is prone to infest the peppermint fields of Michigan, and its oil is said sometimes to deteriorate the oil of peppermint from that region. It has been shown however, that Erigeron (Leptilon) canadensis L. is far more injurious (see Erigeron).
