Health Benefits of Stonebreaker

Stonebreaker has been used traditionally in Ayurvedic medicine and is a hot subject of research today. More studies are needed to ascertain the extent of stonebreaker's effectiveness in people, but its antilithic and antiviral properties give it the following medicinal uses:

  • Dissolving kidney stones and gallstones. Living up to its name, stonebreaker aids the passage of stones and also prevents their formation.

  • Treating hepatitis B. Preliminary studies have shown that stonebreaker can stop this virus from replicating.

Additionally, stonebreaker can quell flare-ups of gout by reducing uric acid levels.

How It Works

Phyllanthin, the most studied compound in stonebreaker, has been observed to have hepatoprotective, anti-inflammatory, and antibacterial properties. In addition, nirtetralin is thought to have antiviral action: studies show that it can inhibit replication of the hepatitis B virus and suppress its antigens, therefore enabling a speedier recovery. However, more research is needed before using nirtetralin to treat other viruses.

Stonebreaker extract helps prevent and treat kidney stones by interrupting various steps in the formation of stones, which are made of uric acid and minerals. The plant's lignans lower blood levels of uric acid, helping to prevent crystal formation. Stonebreaker also reduces crystal clumping and alters the structure and composition of the crystals. The anti-inflammatory activity of the plant can relax the urethra, aiding in the passage of stones.

While its lignans are thought to be mainly responsible for the plant's medicinal actions, stonebreaker also contains flavonoids, tannins, and alkaloids.

Herbs that also protect kidneys' health and improve urination are asparagus, parsley, and angelica.

Stonebreaker Side Effects

Stonebreaker is largely free of side effects. However, a closely-related species, P. amarus, may damage kidneys if used in the long term. Therefore, it is recommended to check with a physician before using stonebreaker.

Stonebreaker flourishes in tropical areas and produces beautiful foliage, but it can adapt to different types of soils and climate conditions.

Growing Guidelines

  • Stonebreaker plants grow well in slightly acidic, wet soils. Though the plant is hardy, adequate organic matter will ensure the nutrient content and soil structure required for proper development.

  • The plant's lateral leaves reach nearly five inches (12 cm) long, so it need to be spaced in rows, at distances of 16 inches (40 cm) between plants and 24 inches (60 cm) between rows.

  • Since stonebreaker grows well in tropical rainforests under partial shade conditions, it may do well in associative systems, such as agroforestry.

    Phyllanthus niruri is divided into two subspecies: P. niruri subsp. niruri and P. niruri subsp. lathryroides. In addition, the plant has over 20 botanical synonyms, though Phyllanthus niruri is the commonly accepted name. P. niruri's common names are also used to refer to a number of other plants in its genus, primarily P. amarus, P. fraternus, P. sellowianus, and P. urinaria. These relatives seem to share at least some of the same active compounds.
