Shevi'is8: 1
כְּלָל גָּדוֹל אָמְרוּ בַּשְּׁבִיעִית: כָּל הַמְיוּחָד לְמַאֲכַל אָדָם, אֵין עוֹשִׂין מִמֶּנּוּ מְלוּגְמָא לְאָדָם, וְאֵין צָרִיךְ לוֹמַר לִבְהֵמָה. וְכָל שֶׁאֵינוֹ מְיוּחָד לְמַאֲכַל אָדָם, עוֹשִׂין מִמֶּנּוּ מְלוּגְמָא לְאָדָם, אֲבָל לֹֹא לִבְהֵמָה. וְכָל שֶׁאֵינוֹ מְיוּחָד לֹֹא לְמַאֲכַל אָדָם וְלֹֹא לְמַאֲכַל בְּהֵמָה — חָשַׁב עָלָיו לְמַאֲכַל אָדָם וּלְמַאֲכַל בְּהֵמָה, נוֹתְנִין עָלָיו חוּמְרֵי אָדָם וְחֻוּמְרֵי בְהֵמָה; חָשַׁב עָלָיו לְעֵצִים, הֲרֵי הוּא כְעֵצִים; כְּגוֹן הַסִּיאָה וְהָאֵזוֹב וְהַקּוֹרָנִית.
A major rule was stated concerning the seventh [year]: Whatever is reserved for human consumption may not be made into a plaster for a person, and surely not for an animal. Whatever is not reserved for human consumption may be made into a plaster for a person, but not for an animal. Whatever is reserved neither for human consumption nor animal consumption — [if] he intended it for human consumption and animal consumption, we apply to it the stringencies of both human [food] and animal [food]; [if] he intended it for [use as] wood then it is [treated] as wood; for example, the savory, the hyssop, and the oregano.
