According to some opinions, a woman can say the thanksgiving blessing ("bentch gomel")
The text that one says is
בָּרוּךְ אַתָּה ה’ אֱלֹהֵינוּ מֶלֶךְ הָעוֹלָם הַגּוֹמֵל לְחַיָּבִים טוֹבוֹת שֶׁגְּמָלַנִי כָּל טוֹב
and what I see listed for the response is
מִי שֶׁגְמַלְךָ כֹּל טוֹב הוּא יִגְמַלְךָ כֹּל טוֹב סֶלָה
That is written in the masculine, I believe. But if the only one saying the blessing is a woman, would the response be refigured to be in the feminine? I have not found any texts that provide the female construction – if one knows of one, please pass it along.
