A root native to Kinmen islands, in the Taiwan Strait. Wild-harvested rather than farmed at scale.

Local record traces its use back to the Koxinga era in the 1660s, when soldiers stationed on Kinmen are said to have first turned to the root for relief. It has remained a staple of herbal practice for hundreds of years.

Gathered wild in limited seasonal quantity, with roots typically harvested after three years of growth, in autumn and winter.

The use of heated minerals for therapy stems from centuries-old Asian practices, including Korean jjimjilbang saunas and heated stone beds.

Practitioners historically relied on materials like jade and volcanic stone, believing their natural warmth could help balance the body's energy, or Qi.

Today this heritage is modernised across Taiwan, Japan and South Korea, using high-temperature sintering to grind minerals into ultra-fine powders, embedded into fabrics and heat therapy products.

A mineral valued for its heat-retaining properties. Tourmaline is naturally piezoelectric — when heated, it generates a small electrical charge and emits far-infrared wavelengths.

Mined globally, including Brazil, parts of Africa, and China.

Unlike Yi Tiao Gen or turmeric, tourmaline is a modern addition — valued for its warming function.

Native to South and Southeast Asia, with India historically the largest grower. Also long cultivated in southern China.

Known in Chinese medicine as jiāng huáng, turmeric has featured in Chinese and South Asian herbal practice for well over a thousand years, valued for its warm, earthy character.
