Pesachim2: 6
וְאֵלּוּ יְרָקוֹת שֶׁאָדָם יוֹצֵא בָהֶן יְדֵי חוֹבָתוֹ בַפֶּסַח: בַּחֲזֶרֶת, וּבְעֻלְשִׁין, וּבְתַמְכָא, וּבְחַרְחֲבִינָא, וּבְמָרוֹר. יוֹצְאִין בָּהֶן בֵּין לַחִין בֵּין יְבֵשִׁין, אֲבָל לֹא כְבוּשִׁין, וְלֹא שְׁלוּקִין, וְלֹא מְבֻשָּׁלִין; וּמִצְטָרְפִין לִכְזַיִת; וְיוֹצְאִין בַּקֶּלַח שֶׁלָּהֶן; וּבַדְּמַאי, וּבְמַעֲשֵׂר רִאשׁוֹן שֶׁנִּטְּלָה תְרוּמָתוֹ, וּבְמַעֲשֵׂר שֵׁנִי וְהֶקְדֵּשׁ שֶׁנִּפְדּוּ.
And these are the herbs with which one fulfills his obligation on Pesach: with lettuce, endives, horseradish, charchavinah, and maror. One fulfills his obligation with them whether moist or dry, but not preserved, nor stewed, nor boiled; they combine to the size of an olive; [and] one can fulfill his obligation with their stalk; with demai; [and] with first tithe whose terumah has been separated, and with consecrated property and second tithe that were redeemed.
