Hi!! I would appreciate your concern for your friend as well as your curiosity for treatment under Ayurveda. It is difficult for me to share the treatment regimens as exact medical details will be required. But definitely, the quality of life and execution of daily activities can be improved significantly with help of Ayurveda.

Ayurveda treatment has been found effective on SLE patients but with out analysing the doshas and Nadi of the patient exact treatment protocol can not be suggested.

SLE is characterized by fatigue ,joints pain , swelling , butterfly rashes ,blood clotting problems etc ...Having said that ,it's also to be considered that it has different effects on different patients..It's an auto immune disease hence chemotherapeutic works by decreasing immunity so it can not attack it's own system as SALE attacks different systems of the body ...Here it is as you said kidney functioning ...As far as Ayurveda treatment is concerned ,we have to maintain the rhythm between all doshas so by enhancing the immune level we cure SLE by Ayurveda
