QUALITY ASSURANCE

At SuperFeast, we are committed to bringing our customers the most pure, potent and effective tonic herbs and medicinal mushrooms we possibly can.

Product Sourcing

Our tonic herbs and medicinal mushrooms are grown fully wild (‘wild crafted’), or in conditions that mimic wild environments (‘semi-wild crafted’). Our herbs are ethically and sustainably sourced, and cultivated in line with Taoist Di Tao principles - meaning they are grown in their ancestral homelands of China, Tibet and Inner-Mongolia. The one exception to this is our cordyceps, which are a lab-cultivated and grown on a liquid fermentation medium to ensure they are both gluten free and vegan.

See our article on the Di Tao tradition for more information.

Product Processing

We extract our herbs using either spring water (‘water extraction’), or spring water and rice alcohol - a process known as ‘dual extraction’.

Our processing facility in China adheres to Good Manufacturing Practice (GMP) standards. Good Manufacturing Practice (GMP) is a strict code of conduct governing how products are handled. Our processing facility is GMP certified. 

Product Quality

We place a lot of focus on the quality and purity of our products because we don’t just sell them, we give them to our own families.

Poor quality herbs are not only a waste of money, they also have the potential to be hazardous to our health. Herbs that are not carefully grown and processed often contain high levels of toxic compounds like heavy metals, moulds or pesticides. Possibly even worse than this, is that such inferior quality herbs will not have the intended therapeutic effect.

Our processing facility uses technology like High Performance Thin Layer Chromatography (HPTLC) and UV fingerprints to ensure our herbs are of the highest quality possible.

Heavy Metals

Our customers are right to be concerned about heavy metals in foods and supplements. We routinely test our products in China, Australia and the USA to ensure we are getting thorough and accurate results.

We source our herbs and mushrooms from regions far away from human or industrial contamination and we list the regions we source from on our website for transparency.

We regularly and routinely test our products for the four heavy metals considered the most toxic. These are:

  • arsenic
  • cadmium
  • lead
  • mercury

We use the strict heavy metals guidelines of the Low Heavy Metals Verified Organisation as a benchmark to test our mushrooms. All of our herbs and mushrooms score between A+ and A+++ (meaning they test extremely clean), based on the LHMVO ratings.

However, like any food or herb taken from the earth, our products contain tiny trace amounts of heavy metals. Even with this in mind, our reishi still tests far ‘cleaner’ than farmed organic reishi we sourced from the USA (which we assume is grown on 'organic' grain or wood chips that have a high level of heavy metal contamination).

Our products are incredibly clean in comparison to almost any food or supplement on the market today.

Please contact us if you wish to view our heavy metal test results. We update them regularly to ensure we are continuing to offer the cleanest herbs possible.

Microbiological Testing

We love the healthy bugs we find in our favourite fermented foods like sauerkraut and beer (!), but we don't want nasty bugs in our herbs or mushrooms. So we take care at every stage of our processing to ensure no contamination occurs.

Our products are tested for microbial quality in China, Australia and the USA. We routinely and regularly test for total microbes, yeasts, moulds and pathogens like E. Coli and mycotoxins. Our products are all successfully tested against the guidelines of the American Herbal Product Association.

Pesticides

We refuse to purchase herbs that have been treated with pesticides. We consider our products 'beyond organic' because they are sourced wild or semi-wild and have grown in their pristine ancestral homeland with little-to-no human input. Organic herbs are usually farmed using organic pesticides high in naturally occurring heavy metals.

Our pesticide test results must be, and always are, zero.

Irradiation

We do not irradiate our herbs.

Packaging

Our herbs are hand-packaged at our facility in Byron Bay, Australia. We package them using Miron glass, which we believe preserves the medicinal qualities of our products better than any other glass on the market. Larger product quantities are packaged in resealable foil-lined Kraft bags.

Internal Audits

We are currently auditing SuperFeast to see if we can make our environmental footprint smaller. We are aiming to reduce, or eliminate, our plastic use, switch our warehouse to solar power, implement a jar recycling program, and much more. We'll let you know the outcomes of these audits as we go!
