Milk Thistle Types and Forms

Processing method matters for bioactivity. Seeds are harvested when flower heads turn brown, then dried to maximum 10% moisture. European suppliers often co-source milk thistle with dandelion as both target liver support formulations.

Milk Thistle Origin and Supply

Poland is the largest European producer of milk thistle seed (Silybum marianum), with cultivation in the Lublin and Podkarpackie regions. Seeds are harvested August-September when seed heads turn brown. Argentina offers counter-seasonal supply from the Pampas region with January-February harvest windows, reducing European buyers' seasonal supply risk. China produces milk thistle at scale in Heilongjiang and Inner Mongolia provinces, primarily for silymarin extract processing. Milk thistle fruit (Silybi mariani fructus) is covered by EMA/HMPC community herbal monograph for traditional use in liver support under Directive 2004/24/EC registration requirements.

Bulk Milk Thistle

Milk thistle seeds are moisture-sensitive and must be stored below 10% moisture to prevent mould development. Standard packaging uses 5-25 kg polyethylene bags with moisture barrier properties. Shelf life reaches 18-24 months when stored below 20 degrees Celsius at under 65% relative humidity. Buyers must verify silymarin content per batch as it varies by harvest conditions and storage duration.

Organic Milk Thistle

Poland and Hungary hold EU Organic certification for milk thistle cultivation in established herb-growing regions. Romanian organic milk thistle offers deeper supply depth but less consistent silymarin concentrations. USDA NOP dual-certified supply exists from Polish growers targeting North American export markets.

Milk Thistle Private Label

Consumer formats include 100g resealable pouches for whole seeds, 60-count capsule bottles for powder fill, and 30ml dropper bottles for liquid extracts. Private label MOQs start higher than bulk orders due to packaging complexity. Buyers must specify silymarin content claims before production as this determines extract concentration and regulatory pathway.

Milk Thistle Manufacturers

European milk thistle manufacturers concentrate in Poland and Hungary near cultivation zones, reducing transport costs and maintaining cold chain integrity. Request batch-specific CoAs showing silymarin content, microbiological status, and pesticide residue panels. Nettle and valerian suppliers often carry milk thistle from the same Polish and Balkan regions.
