1. Z notes that this species is also used to clean teeth using the umbel or inflorescence as a tooth pick (i.e. the short flower stalks spreading out from a common point like umbrella ribs that become woody after fruit is ripe)
2. Z quotes various Jewish & Arabic sources for the toothpick use: "A man takes a toothpick before him to clean his teeth' (Bitzah, 4,6); The answer to the Arabic name for this species ""Khilleh" ( i.e. "what is removed from the teeth with a toothpick) is "visnaga” (“misuak”) a toothbrush, a toothpick".
3. Z also mentions the long historical use of this species amongst Arabs for treating asthma & angina.
4. In the recipe for treating gallstones there is addition of "duqet 'adas" which Z adds in parenthesis is Micromeria serpyllifolia (a synonym of Micromeria fruticose). However Hebrew & Arabic names for the Micromeria genus are "zuta " or "zufa" therefore identity of this ingredient is unclear.

Ammi visnaga contains furocoumarins associated with photosensitizing dermatitis. Unsafe in high doses or over long periods. Other side effects include; liver problems, nausea, dizziness, constipation, lack of appetite, headache, itching, trouble sleeping, & ocular toxicity.
