Thriving Homeland · Highland Botanicals

From Local Roots to the World — Origin, Evidence and People in Every Ingredient.

Deep in the mountains of Yulong County, Yunnan, beside the Jinsha River, grows a wild fruit the elders pick with care — Prinsepia utilis (Green Thorn Fruit / Himalayan prinsepia). We are farmers who grew up on this land. In 2025 we came together as the Thriving Homeland cooperative, to turn what the mountain gives — sun, rain, and patience — into things whose origin you can trace and whose claims you can check. From local roots to the world, verified by evidence.

Why Thriving Homeland

Why a cooperative, and why "local roots"?

In Naxi households this oil is a treasure handed down the generations. When a baby was expected, a grandmother would rise early and climb the mountains to find these thorny wild shrubs, picking the ripe purple berries one by one into her basket, then peeling, rinsing them in spring water, drying them in the sun, and slowly pressing out the clear, precious oil. This craft has passed between hearths for centuries.

But tradition alone is not evidence, and a story alone is not a product. In April 2025 the Thriving Homeland (Yulong County) Agricultural Cooperative was registered in Fengke Town — so that what the highland gives can become a traceable, verifiable and sustainable undertaking that lasts: a livelihood shared by the growers who pick, the makers who press, the researchers who verify, and the people who use it.

Featured Species · Prinsepia utilis

The highland "treasure fruit"

Prinsepia utilis Royle (Rosaceae) blooms in deep winter, bears small green drupes in spring, and ripens berry by berry into bright purple-red fruit. Cold-pressed, its seed oil is the local "treasure oil".

From Plant to Ingredient

From one berry to one drop of oil

Hand harvest → peeling & spring-water washing → sun drying → cold pressing → batch records & testing (in progress) → product.

Hand harvest

Fruits ripen individually and are picked by hand in repeated passes (traditional method; formal harvest standards in development).

Initial processing

Peeling, washing in mountain spring water, sun drying — following the traditional sequence.

Cold pressing

Pressed into a clear oil and bottled away from light.

Batch & testing

Batch IDs and third-party testing records (acidity, peroxide value, microbiology) are being built.
