Our tonic herbs and medicinal mushrooms are grown in conditions that mimic wild environments. Our herbs are traditionally and sustainably sourced with longevity for the earth in mind, and cultivated in line with Daoist Di Dao principles - meaning they are grown in their ancestral homelands of China, Tibet and Inner-Mongolia. Read about why we source our herbs from China and are proud of it.
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. GMP is a strict code of conduct governing how products are processed and handled. Our processing facility is GMP certified.
We place a great deal of focus on our products' quality and purity because we don't just sell them, we give them to our own families. Low-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, molds or pesticides. Possibly even worse, 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.
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:
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 on firstname.lastname@example.org 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.
We love the healthy bugs we find in our favorite 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, molds and pathogens like E. Coli and mycotoxins. Our products are all successfully tested against the guidelines of the American Herbal Product Association.
We refuse to purchase herbs that have been treated with pesticides. Our herbs are 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.
We do not irradiate our herbs. Ever.
Our herbs are hand-packaged at our facility in the Byron Shire, 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. Read about the epic properties of Miron here. Please repurpose your Miron! Larger product quantities are packaged in resealable foil-lined Kraft bags. These Kraft bags are not eco-friendly and we are currently on the hunt for more responsible packaging.
We are a pretty conscious and aware bunch at SuperFeast. The environment is super important to us. 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. We regularly undertake an internal waste program and our HQ is now fully solar-powered.
