Our Story


Tirta Usada Holistic Health was founded by internationally recognised homeopath, health scientist and nature lover Tjok Gde Kerthyasa as a natural evolution of his clinical work as a homeopathic practitioner. Outside of his clinical work, Tjok Gde recognised the need for a range of natural everyday remedies for his patients, as well as an offering of educational workshops and retreats in the realms of alchemy, nature immersion and transformational healing. From here, the various expressions of Tirta Usada were born.

Private practice

Tjok Gde practices homeopathy at the Tirta Usada clinic on his ancestral land in Ubud, Bali, Indonesia. To make an online or in-person appointment, please visit our bookings page.


Tirta Usada will soon release a line of herbs, creams and other holistic products designed to nourish the land, enrich the community and inspire the spirit. Most of the plants in our products are grown naturally and harvested by hand in our gardens at the foothills of Mount Batukaru, central Bali. Homeopathy, alchemy, naturopathy, indigenous Indonesian herbal medicine and other schools of healing form the foundation for every Tirta Usada remedy, each handcrafted with care in our laboratory.

Workshops and retreats

Tjok Gde hosts regular online workshops, live masterclasses and nature-based group retreats in Bali, Indonesia. For scheduling, bookings and more course information, visit our Workshops page.
