śītapānīyasaṃsparśācchītakāle viśeṣataḥ |

sarāgakaṇḍūḥ śophaḥ syādudardaḥ sa kaphodbhava iti ||

tailaṃ ca dārvīviḍaṅgakampillakaiḥ granthivraṇasādhanaṃ sādhayet ||

From contact with cold water, especially in cold weather,
there occurs a red, itchy swelling; that is udarda (urticaria), arising from kapha.

And one should prepare an oil with dārvī, viḍaṅga, and kampillaka, which heals glandular swellings and ulcers.
