Tribulus Tincture & Alcohol-Free Extract

Tribulus (Tribulus terrestris) is puncture vine or goat's head, a prostrate annual of the caltrop family, Zygophyllaceae, native to the warm, dry regions of the Old World from the Mediterranean to India and China and now a weed of roadsides and dry fields across the Americas, including Hawaii. Its hairy stems trail outward for a meter from a central taproot, with small pinnate leaves of five to eight pairs of leaflets and solitary yellow five-petaled flowers. The fruit splits into five woody, spiny nutlets sharp enough to puncture bicycle tires. We extract the dried fruit.
