Puha

 also known as sow thistle or milk thistle (not to be confused with St Mary’s Thistle, also called milk thistle).

 Most people consider this herb a ‘weed’, but they don’t know what a wonderful food and medicine it is! It’s a member of the Asteraceae family (previously known as Compositae) and originates in Europe and Asia, this herb as spread to most lands, including New Zealand.


Identification & Cultivation

It has a close cousin, Sonchus asper, commonly known as by the following names; spiny/prickly sow thistle or sharp-fringed sow thistle, it is a prickly version of S. oleraceus. It is introduced, as is S. asper. The species native to NZ is S. kirkii, a biennial-perennial, which is more bitter than S. oleraceus. They all contain milky sap and have similar bright yellow composite flowers, which bloom from spring to late summer mostly, followed by ‘parachute-like seeds’. The foliage of S. oleraceus is a dusky blue green, though the new shoots are a brighter green and the main stems are hollow. Propagation is by seed; maybe the wind has blown some seed into your place? It prefers to grow in full sun, but can grow in most soils or positions.

Parts Used: Leaves, new shoots, flower buds and sap (topically).

Harvesting: Generally from early spring to midsummer, it gets bitterer into autumn. It does often respond to a prune in autumn, which prolongs its harvest time.

Some of these names allude to the fondness of some animals! The sap can be collected and when dried can be chewed, like gum.

Its botanical names are derived from Greek; Sonchus is for hollow, oleraceus, because it is an ‘esculent vegetable’. Back into ancient history this herb was used as both a food and as medicine. Pliny wrote that Theseus ate a dish of this vegetable before his rendezvous with the bull at Marathon. Culpeper (1616-1654) states that it is ruled by Venus and that “they are cooling, and good against obstructions... the same nature of Dandelion, aperative, diuretic and good for gravel and stoppage of urine. Country people boil it in a posset drink and give it in fevers; some intermingle young shoots among their salads, like lettuce...”

Mrs Grieve wrote that “sheep and goats eat it greedily, but horses will not touch it”.


Culinary Uses: Apparently Captain Cook used this vegetable, boiled up to cure scurvy (vitamin C deficiency) affecting his crew. This is such a versatile vegetable; cook like spinach.


 Maori have traditionally used this herb to treat stomach ailments (as a drink), as a tonic and for women during childbirth, to assist the placenta removal, with reducing the risk of haemorrhaging. Also as a general tonic for the ailing, for digestive disorders, also, for those afflicted with boils or infected wounds, and to ‘detox’ from Katipo spider bites. The milk sap was included in the ‘ink’ preparation, used for tattooing. The Maori Tohunga utilised this herb in some of their sacred rituals.
