Ayurveda therapist

As Beppi pointed out, one would really need to get licensed as a "Heilpratiker". But to start up a practice as a foreigner is difficult. I can only imagining this working out by associating with another person or group who thinks someone specialized in Ayurveda would complement what they already offer. Or possibly one could find support through a yoga school or other association that could give referrals to clients.

Germany allows such things and homeopathic medicines, for example, are readily available in normal pharmacies. But such things are also not recognized as effective mainstream therapies and thus are not covered under normal medical insurance. One also needs to communicate. It is a plus that you know so many languages but I have to question your proficiency. One would expect English to be a Sri Lankan's second language. I would hope your German is better than your English, which to be honest is not very good.
