However, you can use these options depending on the context:
* நீர்க்கொடி (neerkkottai): This literally translates to "water vine" and can be used for a variety of climbing plants, including some species of comfrey.
* நீர் மூலிகை (neer mooligai): This means "water herb" and is a broader term that might include comfrey.
* சூரியகாந்தி இலை (sooriyakanthi ilai): This translates to "sunflower leaf" and can be used for the leaves of some comfrey varieties, particularly those with large, hairy leaves.
It's important to note that the best translation will depend on the specific species of comfrey you're referring to.
If you can provide more context, like the specific comfrey species or how it is being used, I might be able to provide a more accurate translation.
