We have instituted an In-House testing program for bulk herbs for which it would be cost-prohibitive to include in our regular Premium Grade program. These are herbs of which a very limited number of pounds are sold each year and that are not currently in our Premium-Grade, Tested-Grade or Organic-Grade testing programs. As with our other testing programs only an ND (None Detected) result is accepted for herbs to which this test is applied.
Although we feel that in-house testing is inherently less optimal than testing in an independent laboratory, we have a great deal of confidence in our supplier’s in-house laboratory. This trust stems from our experience with the in-house lab of this company. We have purchased herbs from them for more than ten years and have confirmed their in-house testing of each lot we purchased with a test in an independent laboratory. In no instances did the independent lab findings differ from those of the in-house laboratory. The in-house test includes testing for 278 pesticide residues.
Spring Wind Granules are all subject to this same testing protocol; this applies to both single herbs and formulas.
Our supplier’s in-house laboratory is equipped with more than 50 advanced testing instruments including LCMS (Liquid Chromatography coupled to Mass Spectrometry), GCMS (Gas Chromatography coupled to Mass Spectrometry), AA (Atomic Absorption Spectroscopy), HPLC (High Performance Liquid Chromatography), GC (Gas chromatography), Automatic Dissolution tester, TLC (Thin-layer chromatography) scanner and IR (Infrared spectroscopy) testing equipment and is certified by both Chinese and international agencies.
Using the sophisticated laboratory equipment mentioned above the lab has the ability to test for a large number of pesticides (at this time a test for 278 pesticide residues is performed on all P-IHT herbs and concentrates), 45 antibiotics (such as streptomycin, chloramphenicol, tetracycline, carbofuran, fluoroquinolones and sulfonamides), heavy metals ( including lead, arsenic, mercury, cadmium, copper, potassium and aluminum), solvent residues (such as methanol, ethanol, acetone, ethyl acetate, dichloromethane, chloroform, isopropyl alcohol, and benzene), polycyclic aromatic hydrocarbons, plasticizers aflatoxins, artificial pigments, sulfur dioxide, and microorganisms (total count numbers for bacteria, mold and yeast, as well as testing for the presence of coliform bacteria, Escherichia coli, Salmonella, Pseudomonas aeruginosa and Staphylococcus aureus). In addition to organoleptic herb identification performed by persons educated in that specialty, the lab uses testing via chemical identification, thin layer chromatography and infrared spectroscopy to confirm identification of herbs.
In summary, we have chosen to use the Premium-In-House-Testing (P-IHT) protocol to screen herbs that we have previously not tested for pesticide residues. This will increase the number of herbs tested to well over 300 herbs and will now include many herbs that are not frequently used and were previously categorized as Conventional Grade. Further, we will use this grade designation for the vast majority of our concentrated granules (we will continue to confirm the results at an independent laboratory for herbs we have found to be troublesome in the past). The test includes 278 pesticides and this residue list includes all pesticide residues that we have discovered in herbs in our 30 year history of testing herbs for pesticide residues.
