Broccoli Seed Tea is not available as a commercial product like a herbal infusion. A step by step guide has been prepared to help you buy the right seeds and make Broccoli Seed Tea containing fully bioavailable sulforaphane at home. This guide is accessible with *Premium Membership.

.

• Broccoli Seed Tea (BST) is not a traditional herbal infusion. To make sulforaphane requires a two-step process. In the first step, the seed contents, including Glucoraphanin, are extracted into boiling water. In the second step, an active enzyme, Myrosinase is added in the form of ground white mustard powder (sinapis alba).The Myrosinase digests the Glucoraphanin by cleaving off a Glucose molecule.  The remaining part of the molecule is then reorganized to make the bioactive molecule Sulforaphane. The process looks like this:

.

.

.

• The process of digestion of glucoraphanin by myrosinase is strongly temperature dependent. To obtain a good yield of sulforaphane, the ground white mustard powder must be added to the seed extract at a precise temperature and enough time must be allocated to allow the process to complete. These parameters have been optimized to deliver a high yield of sulforaphane in the shortest possible time.

.

• The Broccoli Seed Tea used in research published on this site was made using a special batch of seeds which had been analyzed in a laboratory to know its precise glucoraphanin content (78 micro mol or 34 mg of glucoraphanin per g of dry seeds). The preferred unit of measure is “mol” where 1 mol = molecular weight (MW) of the molecule in g, because of its equivalence independently of size or weight of the molecule. 1 mol of glucoraphanin (MW 437,5) will be converted into 1 mol of sulforaphane (MW 177.3) if the yeild is 100%. Therefore in 1 g of these seeds, 78 micro mol, or 34 mg of glucoraphanin could be converted into a maximum of 78 micro mol or 13.8 mg of sulforaphane. We only have a limited stock of these seeds and they are not for sale.

.

• Only certain types of broccoli seed are suitable for making BST. Broccoli seeds that are sold commercially vary considerably in the amount of glucoraphanin they contain (from 20 to ~100 micro mol/g), but seed vendors rarely know how much glucoraphanin they contain, because they will not have not been analyzed. Furthermore, some seeds labelled as broccoli are cross-bred varieties genetically close to turnips and contain zero glucoraphanin. To avoid mistakes and buy the right seeds reliably requires either expert knowledge and experience or careful guidance. Detailed instructions and information are now available to enable you to become experts but also to purchase good seeds without wasting valuable time by following simple instructions and consulting a list of trusted online seed suppliers.

.

• To reproduce this method and make Broccoli Seed Tea consistently at home means buying some specific, but inexpensive equipment. This tea-making kit has been tested to ensure that it works well and a list of online equipment suppliers is provided.

…

To make BST available for home use, detailed information is now available at several levels.

1. Detailed scientific and technical information for those who wish to become experts
2. Clear explanations, instructions and links to trusted online suppliers, to enable you to purchase all you need to make BST without losing precious time.
3. To make BST affordable for home use, you will find a list of reccommended tea-making equipment that can be purchased for around $120. This BST kit has been tested to ensure that it works well. A list of online equipment suppliers is also provided.
4. Easy-to-follow instructions for purchasing suitable broccoli seeds and making high-quality broccoli seed tea consistently.
5. A space for BST users to meet and exchange information with other users. This is particularly helpful for new users.

…

Once you are ready, follow the step-by-step instructions to make BST consistently. You will become an expert in no time.

…

These instructions, with helpful links to various websites, seed and equipment suppliers, as well as the most useful research articles, are available as a service with online help via Premium Membership.

About Broccoli Seed Tea and sulforaphane
Sulforaphane has been studied for over 25 years and is believed to have health benefits. However, broccoli seed extracts with sulforaphane, such as Broccoli Seed Tea, have not been tested for safety or benefits in people with Parkinson’s disease in official clinical trials. Therefore, reported benefits of sulforaphane from broccoli seeds should not be viewed as proof of safety or effectiveness. Only approved clinical trials with many participants provide evidence for the safety and efficacy of drugs and therapies.

…
Broccoli seeds contain glucoraphanin, the precursor to sulforaphane, but the amount can vary greatly by broccoli variety. Additionally, the composition of the resulting solution, regarding sulforaphane and other compounds, depends heavily on the quality of the seeds used. Thus, any product made from broccoli seeds bought commercially will differ significantly from the Broccoli Seed Tea discussed in research articles on this site.

BST Data Sheet
Before signing up for a Premium membership, please read carefully the information and warnings regarding the potential health hazards associated with consuming substances derived from broccoli seeds. In addition to sulforaphane, the final product made from broccoli seeds will contain unknown quantities of other substances, some of which are known to be toxic, including seed oils, erucic acid, thiocyanates and nitriles. Thiocyanates can affect thyroid function by interfering with iodine uptake. The products of this procedure have not been approved as safe for human consumption by any food or medical authority. Consuming the products of this procedure may interfere with other medications and present a danger to your health. Never disregard professional medical advice or delay seeking medical treatment because of something you have read on or accessed through this website. Please note that the final product made by any individual from commercially available broccoli seeds will always be significantly different from the Broccoli Seed Tea referred to in research articles on this site. In addition to the subscription fee, the suggested method for making Broccoli Seed Tea entails the purchase of equipment and materials estimated at around $120.
