Product Information


Latin name: <i>Silybum marianum</i>

Family: Asteraceae/Compositae 

Common names: Milk thistle, holy thistle, silybum

Parts used: Fruit


St Mary’s thistle is an annual or biennial plant that grows anywhere from 30cm to 3m in height. Native to the Mediterranean and areas of south-western Europe, it is also naturalised throughout New Zealand and southern and eastern Australia. St Mary’s thistle grows in rocky areas and wastelands and is classified as a noxious weed in many areas as it is rapidly self-sowing, difficult to handle due to its sharp spikes, and difficult to control. The herb is robustly drought and frost resistant and quickly permeates large areas of land. Each stem of St Mary’s thistle bears a large purple flower surrounded by sharp spines. Its common name ‘milk thistle’ refers to its distinctive spiky, white-veined leaves that yield a sap when crushed and was believed to contain the Virgin Mary’s breast milk.
