I'm not sure whether the western countries/people even get it about Ayurveda.

Only people who can restrain, understand their body type and be patient can be cured by Ayurveda, because Ayurveda is at the core is a therapy and taking herbal pills or syrups alone won't be of any use.

Do all Ayurvedic spa do such activities where you live?

In India Ayurveda is attached to religion and culture and in normal cases the advice is free of cost. Because people generally know and believe in the power of Yoga here, it works for most of them in most of cases.
