Cumae (Ancient Greek: Κύμη (Kumē) or Κύμαι (Kumai) or Κύμα (Kuma);Italian: Cuma) was an ancient city of Magna Graecia on the coast of the Tyrrhenian Sea. Founded by settlers from Euboea in the 8th century BC, Cumae was the first Greek colony on the mainland of Italy and the seat of the Cumaean Sibyl. The ruins of the city lie near the modern village of Cuma, a frazione of the comune Bacoli in the Province of Naples, Campania, Italy.
Cumae is perhaps most famous as the seat of the Cumaean Sibyl. Her sanctuary is now open to the public.
In Roman mythology, there is an entrance to the underworld located at Avernus, a crater lake near Cumae, and was the route Aeneas used to descend to the Underworld.
The settlement, in a location that was already occupied, is believed to have been founded in the 8th century BC by Euboean Greeks, originally from the cities of Eretria and Chalcis in Euboea, which was accounted its mother-city by agreement among the first settlers. They were already established at Pithecusae (modern Ischia); they were led by the paired oecists (colonizers) Megasthenes of Chalcis and Hippocles of Cyme.
SierraSil is a dietary supplement marketed for joint pain relief. SierraSil is a combination of 65+ natural minerals that have been proven in studies to "shut off the genetic switch to inflammation". SierraSil has been used clinically to relieve the pain of injury, fibromyalgia, colitis, and many other sources of pain.
A study in the Journal of Inflammation reported that SierraSil on its own or in combination with Cat's claw provided relief of osteoarthritis symptoms. Another study printed in The Journal of the American Nutraceutical Association concluded that SierraSil can significantly reduce processes associated with cartilage breakdown. Results of a mechanism of action study to determine how SierraSil worked on human cartilage in-vitro showed a reduction of the breakdown of cartilage by 68 to 73%, measured by the reduced amount of degraded cartilage debris, as glycosaminoglycan (GAG) release, likely due to suppression of gene expression.
In the early 1970s, while searching for gold in the high Sierra Mountains, a prospector discovered clay that sparkled when exposed to sunlight. The mineral compound found in the clay was a result of thermal forces that occurred in the area and is similar to those used in traditional remedies by indigenous peoples, including Native Americans, who for thousands of years have used mineral-rich clay powder for its healing properties. Mineralogist Haydn H. Murray, Professor Emeritus of Indiana University, concluded after conducting an x-ray diffraction analysis of SierraSill that an underground hot water solution in the area resulted in a very unusual and rare mineral suite, unlike any other he had seen in his more than 50 years of research.
