Echinacea Similar to the chamomile cross reaction, echinacea can induce allergy symptoms in people with an existing ragweed allergy because of the shared plant family. Echinacea is often used to relieve symptoms similar to allergies, such as sore throat from colds and flu.
The adults are recognizable by their (usually five-point) radial symmetry, and include such well-known animals as starfish, sea urchins, sand dollars, and sea cucumbers, as well as the sea lilies or stone lilies. Echinoderms are found at every ocean depth, from the intertidal zone to the abyssal zone.The phylum contains about 7000 living species, making it the second-largest grouping of deuterostomes (a superphylum), after the chordates (which include the vertebrates, such as birds, fishes, mammals, and reptiles).ll echinoderms are marine and nearly all are benthic. The oldest known echinoderm fossil may be Arkarua from the Precambrian of Australia. It is a disc-like fossil with radial ridges on the rim and a five-pointed central depression marked with radial lines.
