#FoeniculumVulgare

From bustling Thai markets with the intoxicating aroma of herbs to age-old remedies passed across generations, few herbal medicines weave as rich a tapestry of tradition and science as เทียนข้าวเปลือก (tian khao pleuak), internationally known as sweet fennel or by its botanical name, Foeniculum vulgare Miller subsp. var. vulgare. Renowned locally as “ยี่หร่าหวาน” or “เทียนแกลบ,” this versatile spice and medicinal plant sits at a fascinating crossroads—honored by Thai healers for its soothing properties and now increasingly validated by global pharmacological research.
