Plants that belong to the Atriplex genus are commonly referred to as saltbush or orach, mainly due to their unique ability to store salt in their leaves. This allows them to grow in highly saline environments, making them useful for rehabilitating soils that have high salt concentrations on the surface. Saltbush fulfills this function by getting moisture from deep within the soil, lowering the water table and disrupting the upward movement of moisture.
In the study, the researchers looked at A. lasiantha, a type of saltbush native to Pakistan. They obtained extracts from the aerial parts of the plant using different solvents and subjected the extracts to different assays to determine their antioxidant, antifungal, and anti-parasitic properties. The researchers also evaluated the extracts' ability to inhibit bacterial growth, as well as their anti-cancer and hemolytic activities.
The findings of the study were positive: Based on multiple in vitro tests, the researchers found that A. lasiantha can inhibit the proliferation of cancer cells. However, they recommended that further studies be done to identify the compounds at work for this biological activity. In addition, they also noted that the extracts possess potent antioxidant properties, thanks to the presence of different polyphenols in A. lasiantha.
For its anti-parasitic properties, the researchers used Leishmania tropica, a protozoan parasite often transmitted by sandflies. These parasites multiply in the body and cause a disease called leishmaniasis, which can cause skin sores and internal organ damage. The researchers found that this particular species of saltbush contains compounds that can effectively address the infection.
"The current study reveals the potential of Atriplex lasiantha Boiss for the discovery of biologically active compounds through bioassay-guided isolation against various diseases," the researchers concluded in their report.
Saltbush is found in many regions around the world, including Australia, South America, and even North America. The fourwing saltbush (A. canescens) is endemic to the Midwest and West, and Navajos parch them to make flour.
In terms of nutrition, saltbush is packed with:
Although the plant gets its moniker from salt, eating it is actually beneficial for overall health.
People who eat saltbush describe its taste as tangy and similar to chard. This might make it less appealing to others, but that didn't stop the Russians from eating it during the siege of Leningrad. They used saltbush to make soup and bread — together with machine oil.
