The Persian/Sanskrit word, Kirpas, means "a fine linen."

Remember Joseph's brothers dipped his fancy coat in blood after selling him into slavery
—Genesis 37:31

Another Persian word, Karafs, means "a plant of which a salad is made." A Greek word, Karpos, means "fruit of land/rivers."*

Rather than dipping fine linen in blood, dip the parsley or celery into salt water.

בָּרוּךְ אַתָּה יי אֱלֹהֵינוּ מֶלֶךְ הָעוֹלָם, בּוֹרֵא פְּרִי הָאֲדָמָה

Blessed are you, God, ruler of the universe, who brings forth fruit of the earth.
