Alvita chooses only the highest quality organic, wildcrafted, or cultivated botanicals, perfectly prepared to provide you with the best Mother Nature has to offer. Historical and scientific literature is painstakingly studied to ensure that the correct traditional plant and most appropriate servings are used, delivering premium flavor and quality.

Milk Thistle Native to the Mediterranean region, milk thistle (Silybum marianum) gets its name from the milky white sap that is found in the leaves and stem. Amazingly, all parts are edible, but European herbalists have traditionally used the seeds to help alleviate stomach upset.

Alvita Milk Thistle Tea is made with premium-quality, organic milk thistle seeds, and has a pleasantly delicate flavor.

Certified Organic by QAI.

Alvita Since 1922

USDA Organic

Quality Assurance International Certified Organic Star-K (Kosher)

The Alvita Story… In 1922, a new era for tea consumption began in America. The herb alfalfa, long known for its beneficial nutrients, was packaged in tea bags and sold to an emerging health food market. This product became known as Alvita and set the standard for future herbal teas. Today, Alvita represents more than forty single-ingredient teas, each one uniquely distinct, just like the individuals who drink them.

Herbs are gifts from the earth. Alvita takes its stewardship seriously by offering carefully harvested teas in earth-friendly packaging. Our beautifully illustrated boxes are made using recycled paperboard and our English, pillow style tea bags are oxygen bleached, not chlorine treated. You won’t find a better product, with a cleaner package… anywhere. Alvita… brewed with confidence, steeped in tradition.
