Their team of pharmacists and botanists provides technical support, helping clients navigate regulatory requirements for product registration.

West Nusa Tenggara Naturals, located in Mataram, Lombok, is a small-batch producer with a focus on artisanal milk thistle extract. Founded in 2017 by a group of herbalists and farmers, the company embodies the spirit of "slow extraction," prioritizing quality and tradition over speed and volume.

Their milk thistle is grown on family-owned farms in Lombok's mountainous regions, where the seeds are hand-harvested and sun-dried to preserve nutrients. Extraction is done using a traditional maceration method—soaking seeds in organic grape alcohol for 4–6 weeks—followed by gentle evaporation to retain volatile compounds often lost in industrial processes. The result is a rich, dark extract with a complex phytochemical profile, popular among natural health practitioners and boutique skincare brands.

West Nusa Tenggara Naturals offers only organic certified milk thistle extract, certified by Organic Indonesia and Fair Trade. Their product line is small but focused: a liquid extract (for tinctures and skincare), a powdered extract (for supplements), and a raw seed oil (used in soaps and balms). Minimum orders start at 250g, making them ideal for small businesses and hobbyists. While their production capacity is limited (around 50 metric tons per year), clients value the story behind the product—knowing their ingredients come from sustainable, community-driven farms.
