Description
Silymarin is a milk thistle flavonolignan complex, and Pure Rawz sells it as capsules. Every batch is tested for 99% purity or better, and it’s sold for laboratory research only.
Silymarin explained
Silymarin is a mix of flavonolignans from milk thistle (Silybum marianum) seeds. Silybin is the main component.
It’s been used for liver complaints in Europe for centuries.
How it acts in research models
Silymarin is an antioxidant, blocks toxin uptake into liver cells and raises protein synthesis in the liver. It also lowers inflammatory signaling.
Its absorption is low, which is why some products combine it with phospholipids.
What studies say about Silymarin
Trials in liver disease have been mixed. A 2007 Cochrane review didn’t find clear benefit in alcoholic or viral liver disease, while lab work shows liver-protective effects.
Intravenous silibinin is used in Europe for death cap mushroom poisoning.
The primary literature is on PubMed. Here’s a search to start from.
Options and prices
This listing is a bottle of 60 capsules, 150mg each, for $11.45.
Capsules hold a measured amount each, listed in the size option with the count and total.
Using Silymarin in the lab
Plant extracts contain many compounds, so a common design compares the whole extract with its main isolated compound to see which effects come from which.
Write the extract ratio or standardization into your methods. It’s the detail reviewers ask about first.
Endpoints depend on the plant: immune markers and cytokines for mushroom beta-glucans, glucose and lipids for metabolic botanicals, or behavior tests for calming plants.
