If there is any doubt concerning plant or marine extract identity, we perform a micrographic test. Likewise, the moisture percentage is analyzed by the gravimetric methods. The ash determination is also measured.

Next, we perform a microbiological, sanitary analysis which includes the determination of the most probable number of microorganisms (NMP/g) through the methods recommended in the International Pharmacopoeias. Mould and yeast recount is performed. The finished products require additional analysis which include an aerobes recount on the plaque and microbiological analysis.

Then a Thin Layer Chromatography (TLC) test is conducted on each batch, which is a sophisticated means of identifying the makeup of individual substances in a given compound. This unique fingerprint confirms the chemical composition, concentration, consistency and authenticity of each and every herb we use, but also allows us to use only the most high-quality herbs available.

Following the TLC test, a specific active principle assessment is made by High Performance Liquid Chromatography (HPLC).

We also formulate and prepare our products based upon the documented use under traditional medical systems; guarantee that the correct species of plants shown on the labels matches what is in the bottle; utilize sustainably grown and wild or organically harvested plants and marine products that are the freshest and highest quality plants possible but are also free of chemicals, preservatives, additives, fillers or contaminates.

Further testing for moisture content, dissolution, heavy metals (lead, arsenic, mercury, cadmium) and microbial content are performed on every batch, including Aristolochic Acid and Chloramphenicol testing.

When the products arrive in the United States for manufacturing, they are reviewed by the U.S. Food and Drug Administration and US Customs to further guarantee that every element that goes into Natura Petz herbals and supplements meets the absolute highest standards for purity and safety.
