8th-11th October 2020 – London

The themes of the seminar will include Lyme disease, migraines, chronic insomnia, dementia, Parkinson’s, arthritis, CFS and neuro disorders (OCD, and paediatric ones with bacterial links).

These conditions will be illustrated with cases from his own practice, and how he arrived at the prescription in each case. Following on from the November 2019 seminar Ton will again show how to use blood analysis to help understand and treat our patients.

** Please note: it’s essential you study the book ‘Fighting Fire with Fire’ by Ton Jansen before the seminar.** A few copies are still available and a third edition is being printed, available to buy from humanchemistry.eu or https://www.emryss.com

During this 4-day seminar we shall cover the following:

In the first hour, any outstanding questions on the method for those newer to HDT.
Then some new developments in the HDT method.
Further exploration of blood analysis where Ton will demonstrate:

  • links he has found between more blood markers and disease.
  • more on how to resolve vitamin and mineral imbalances using remedy courses and supplements
  • how to correct imbalances in white blood cell count as well as hormones and other factors
  • more detail about such conditions as Hepatitis, Helicobacter and Herpes.

Ton’s teaching will include:

+MATERIA MEDICA: Ton has an extensive knowledge of Materia Medica and will provide insights into new and existing remedies in a way we have not understood them before. We shall review sarcodes and nosodes such as Pancreatic Enzymes, GC-Maf, Bone Marrow, Saponins, as well as the Poly combination remedies, and how to manage cases with them.
+ORGAN SUPPORT: we shall review at the hierarchy of organs and systems and how to manage detoxing, specifically starting with the endocrine system. Ton will show us how he supports organs using both remedies and orthomolecular supplements.
+LIVE CASES: this will be an interactive seminar where we go through 2 live cases per day. This will allow us to grow familiar with the method in practice, cover different disease patterns and look at miasms.

A certificate of attendance will be awarded to those who are attending an HDT and Human Chemistry Seminar for the first time, and a diploma will be awarded to those who are continuing to develop their knowledge and practice of HDT and Human Chemistry.


Ton released this new book in 2019, full of the materia medica of plant remedies, with case histories and beautiful photos of the plants.
