In Tree Shade Therapy of your area the Healers suggest patients with poor vitality to sit in shade of this tree up to specific time.

It reminds about another Dipterocarpaceae member Shorea. Please see attached Ecoport pictures.

Shorea I think usually has 3 wings (now five with the merger of Parashorea)
Your plant has 5 wings, which should be Parashorea stellata Kurz, now correctly known as Shorea stellata (Kurz) Dyer
The plant uploaded by … has two wings, characteristic of Dipterocarpus (fruiting calx free from ovary; stipules large) and Anisoptera (fruiting calyx adnate to fruit; stipules small).

I have attached a photo of Gyrocarpus asiaticus? to some extent the winged seeds are look like of D. t. !

Considering the image with leaves that is available online by the same person (…) who posted this picture, this is most probably Dipterocarpus turbinatus. More details would be helpful for further clarification.
