What type of collection does Etarcomol and Medb have in common?
Etarcomol Etarconol is a character from the Ulster Cycle in Irish folklore. He is the son of Eda and Léthrenn and a foster-son of Ailill and Medb. He was the first champion to face Cúchulainn in single combat. He was killed as Cúchulainn struck down through his crown and split him "to the navel".
Medrysone Medrysone (INN, USAN) (brand names HMS, Medrocort, others; former developmental code name NSC-63278), also known as hydroxymethylprogesterone, methylhydroxyprogesterone, or hydroxymesterone, as well as 6α-methyl-11β-hydroxyprogesterone or 6α-methyl-11β-hydroxypregn-4-ene-3,20-dione, is a synthetic glucocorticoid that is or has been used in the treatment of inflammatory eye diseases. It has been discontinued in the United States. Although it is very similar in structure to progesterone, neither progestogenic nor androgenic activity has been demonstrated for or attributed to medrysone.
