Milk thistle also known as Silybum marianum is a plant native to Europe that has been used for centuries in traditional medicine, particularly for liver and gallbladder disorders. Its seeds contain a group of bioflavonoids known as silymarin, which is believed to have antioxidant, antiviral, and anti-inflammatory properties.
Milk thistle is available in various forms, including capsules, tablets, liquid extracts, and teas. The seeds and sometimes leaves are used in these preparations. However, since the beneficial compounds in milk thistle are poorly absorbed and not water-soluble, teas may not be the most effective way to consume it.
Studies suggest that milk thistle supplements may improve liver function in individuals with non-alcoholic fatty liver disease (NAFLD) by reducing inflammation, free radical damage, and lowering ALT, AST, and GGT blood levels, supporting its liver health benefits1-3. The daily milk thistle dose was based on the required silymarin amount, with clinical studies using doses ranging from 210mg to 1200mg per day for conditions like chronic hepatitis C, non-alcoholic fatty liver disease, and viral hepatitis⁴.
Research shows that type-2 diabetic patients with poor glycemic control who were taking glibenclamide (a drug that stimulates insulin production) experienced significant improvements when supplemented with silymarin. These benefits include reductions in fasting plasma glucose (FPG), protein glycation, and BMI, with better outcomes compared to placebo or glibenclamide alone. The study involved 25 patients, a 4-month regimen of 200mg silymarin taken three times daily before meals significantly reduced blood glucose levels⁵.
A combination of silymarin, n-acetylcysteine, and selenium significantly improved antioxidant levels, reduced inflammation, and decreased acne lesions in patients with papulopustular acne. Silymarin supplementation led to a 53% reduction in acne lesions, highlighting its potential as an effective acne treatment. Patients with papulopustular acne were treated with silymarin 210mg/day (70mg three times daily after meals) and a topical moisturising cream applied once daily at bedtime⁶.
Research studies show that silybum marianum, silymarin, and silibinin may help improve symptoms of rheumatoid arthritis (RA) and osteoarthritis (OA). It showed that taking silymarin (300mg/day) for 8 weeks reduced inflammation by 56-58% in osteoarthritis patients⁷. Additionally, a study showed that silymarin treatment for 8 weeks reduced the worsening cycle of inflammation in patients with knee osteoarthritis⁸.

Silybum marianum or milk thistle has demonstrated neuroprotective effects against neurodegenerative diseases like Alzheimer’s, Parkinson’s, and depression due to its antioxidant, anti-inflammatory, and cell-protecting properties⁹. Additionally, research shows that silymarin effectively reduces obsessive-compulsive disorder (OCD) symptoms by decreasing uncontrollable thoughts and behaviours. The study found that 600mg/day of silymarin for 8 weeks effectively reduced OCD symptoms, including uncontrollable thoughts and behaviors¹⁰.
Silymarin has shown multi-target effects on cancer cells, with research supporting its anti-cancer properties in liver, pancreas, prostate, and skin cancers. Its antioxidant and anti-inflammatory properties, along with its ability to regulate proteins and genes, contribute to its chemo-preventive effects at different stages of carcinogenesis, including onset, promotion, and progression11. A study reported that consumption of silymarin (0.1g to 5g/day) for 5 months helped treat prostate cancer, leading to cancer-free tissue in patients¹².
Milk thistle is regarded as a safe herbal product when taken at therapeutic doses, with minimal toxicity reported in pharmacological studies¹³. Some side effects may include gastrointestinal discomfort (such as diarrhea, bloating), headaches, and skin reactions (like rash, hives, or itching). Individuals allergic to plants in the Asteraceae/Compositae family such as ragweed, chrysanthemums, or marigolds should use with caution as milk thistle may trigger allergic reactions¹⁴.
Currently, there is no standardized dosage for milk thistle. However, research provides some guidance on its usage. A 2011 study suggests that adults may benefit from taking 420mg of milk thistle extract (standardized to 70–80% silymarin) three times daily for a period of 6 to 8 weeks. For ongoing maintenance, a lower dose of 280mg per day is recommended¹⁶.
Milk thistle may interact with certain medications, potentially altering how they are processed in the body. Individuals taking medications for liver conditions, diabetes, or hormonal therapies should consult a doctor before using milk thistle to ensure safety and avoid complications¹⁵.
