Are there any good ayurveda treatments for keloids?

No: Keloids are very difficult to manage. Depending on duration and severity, application of vitamin e, cortisone and silicone may help. Sometimes, cortisone may have to be injected or surgery(as a last resort) may become indicated.

Keloid Rx: The safest approach is silicone tape/gel (myscaraway, from walgreens/online), steroid/bleomycin injections immunosuppressant/chemotherapyagent) only in pro hands, electron-beam radiotherapy, almost never excision unless radiotherapy can be guaranteed within 24hr after excision. Be very careful or it will be made worse by cutting it! close follow up for 2yrs+ to monitor for recurrence essential!
