Musnad Abu Ya'la al-Mawsili 109:281

The Prophet (peace be upon him) entered upon Aisha, and with her was a young boy whose nostrils were dripping blood. She said, "He has *al-udhra* (tonsillitis/throat inflammation)." He said, "Do not kill your children. But any woman whose child has *al-udhra* or a pain in his head, let her take Indian incense (*al-qist al-hindi*), then scrape it with water, then let her administer it to him through the nose." Then he commanded Aisha, and she did that, and he recovered.
