EMDR is a therapeutic tool that some therapists use with their clients. It was developed by psychologist Dr. Francine Shapiro in 1989.
Hyssop is used for digestive and intestinal problems including liver and gallbladder conditions, intestinal pain, intestinal gas, colic, and loss of appetite. It is also used for respiratory problems including coughs, the common cold, respiratory infections, sore throat, and asthma.
This plant, or a product of this plant, formed an important part of the Passover (Exodus 12:22), ceremonial cleansing from skin disease (Leviticus 14), and the red heifer offering (Numbers 19). It is perhaps in reference to the latter that David mentions hyssop in Psalm 51:7. 19:29 (discussed below).
