In view of the current difficulties with travel and also places to hold live seminars, we have decided to offer a continuing online course of training in Human Chemistry, covering its underlying principles and how to apply them in cases. For each event we offer a certificate of attendance, but wish to encourage participants to achieve a level of skill in working with cases where we can award them a Certificate of Proficiency in the practice of Human Chemistry. Those who reach this level can go on to do further work on case management, with some research into a chosen aspect of Human Chemistry, in order to gain a Diploma.

The topics that follow in this calendar may be changed according to the wishes of the community of participants. Each two-day webinar can also include live and follow-up cases, related to the themes of the event. Ton will continue to give guidance on using blood-test results to influence our prescriptions, and also teach us about using orthomolecular supplements to enhance our homeopathic remedies.
At all webinars where someone is asking for guidance on case treatment a detailed timeline should be provided, so Ton can readily see that the issues are and his advice can be given more easily.

Thursday 22-Friday 23 April
We shall begin with two adrenal conditions – Addison’s disease and Cushing’s syndrome – picking up from the February webinar. Then look at some different types of herpes conditions. There will also be a brief revision of miasms and their main remedies. The new topic this time will be mental conditions including addictions and depression.

At the end of this event we shall post a case for attenders to work on and prescribe for. Those who Ton feels have done it well will be awarded a Certificate of Proficiency.

Thursday 20 May
This is the first of the one-day webinars, aimed to give an opportunity for more questions than we can answer in the two-day events. These would focus particularly on points from the last webinar needing more clarification, but can also be whatever you want to ask. One question we have already received is about how Ton advises the use of GC-Maf in cases. There will also be a chance for attenders to have guidance in their difficult cases (with a detailed time-line available beforehand!).

Thursday 17-Friday 18 June
In this webinar we shall finish mental conditions including PTSD, and then study neurological conditions including tinnitus and tics.

Thursday 8 July
A one-day webinar where Ton can answer the latest questions, and also help with cases.
(We thought we should keep this date early in July, as it may be possible by then for people to go on summer holidays!)

Thursday 14-Friday 15 October
In this third webinar in this year’s course we shall focus on circulatory conditions (hypotension and hypertension), and then consider how to understand and prescribe for cancer cases.

Thursday 4th November
A one-day webinar to give an opportunity for Ton to answer questions arising from the October presentations.

Thursday 2 – Friday 3 december
In this last two-day webinar of this year’s programme we shall discuss female hormonal conditions including IVF, and then review the treatment of a variety of allergies.

Thursday 16 December
This will be the final one-day webinar of the year, giving us the chance to ask all those pending questions – arising from the November event, but other topics as well. And seek help with cases too.

‘Intervision’ meetings will continue as wanted, both as smaller meetings in various time-zones and as fuller meetings internationally. Please give your ideas and feedback on these meetings!

The webinars will be as interactive as possible (and also secure), as by using Zoom for Webinar the presenter can see the faces of those attending. Questions can be asked via the raising-hand facility at question times.

We are going to test out a change in the timings: the webinar will start at 0830 UK summer time (BST), with a break from 10-1030; the second sessions will run 1030-12 noon. The lunch (or breakfast) break will run from noon till 1.30pm (to give time for eating and a little exercise perhaps). The third session will run from 1.30 till 3, then a half-hour break; with the final session 3.30-5pm. So this way we have six hours’ teaching per day! By starting early this will not suit USA/Canada but we give the Australians a chance of comfortably attending two sessions live; our later sessions will be fine for USA/Canada to attend live but will be too late for Australasia. (The afternoon sessions are not a repeat of the morning!). The longer breaks can also let us rest our eyes and move about a bit during the day. There will be a recording available soon after each day, to watch but not to download – but subject to the usual rules of confidentiality.

There may still be people attending who will be new to Ton’s system. So please note: **it’s very advisable you have studied the book ‘Fighting Fire with Fire’ by Ton Jansen before the seminar. This book is available to buy from

A certificate of attendance, showing hours attended for CPD purposes, will be issued after the event. We shall also send you a case to work to prescribe for after the webinar, to give you a chance to be awarded a Certificate of Proficiency.

Please register by emailing me at the address below. The fee and payment arrangements for this year’s series of webinars will be emailed as soon as possible Ton is unlikely to be able to resume his visits to other countries for quite some time, so please take this opportunity of studying with Ton from your own home!
