Dr. Sarah Sallon, a pediatrician turned medicinal plant researcher, has dedicated her career to studying and reviving ancient seeds found in Israel. Through the Middle East Medicinal Plant Project, she has successfully germinated and grown ancient date seeds, including a 2,000-year-old seed named Methuselah. Sallon's latest project involves a 1,000-year-old seed from a Judean desert cave, which she believes may be the biblical tsori, a resinous substance mentioned in the Bible for its healing properties. This seed, identified as a Commiphora species, has been characterized through DNA sequencing and chemical analysis, revealing unique medicinal compounds and suggesting a connection to the biblical tsori.
