Kesharim are Jewish bundle amulets. Kesharim in Hebrew is often translated to "garlands" or "knots". Kesharim are referenced in the Talmud, Shabbat 66b:6 - Shabbat 66b:10. Most often, they are interpreted as being akin to medicine pouches or sachets.
Amulets, in general, are also traditionally referred to as kame'ot (singular form: kame'a) in Hebrew. In Yiddish, we would call them beytele, and in Ladino, they're referred to as bulsikas.
Kesharim can be used for various kavanot. Kavanah in Hebrew is often translated to "intention". Kavanot being the plural form of kavanah.
