From flavour to flavonoid: Plant Chemistry and Pharmacology for herbal medicine practitioners

A two day workshop presented by Dr Christopher Etheridge PhD MCPP

Organised by the The White Crane Academy of Chinese Herbal Medicine

8-9th December 2018, 9.30-17.30

At The Nash Lecture Theatre, Kings College London, Strand Campus, WC2R 2LS

Learning Objectives for the workshop

Day 1 will cover content that is directly relevant to experienced practitioners as well as students. There will be necessary revision of the theoretical understanding of plant substances and analytical methods, as this may have changed a lot since the practitioner did their original training courses (techniques like HPTLC have only been used routinely in the last few years).

The two days are designed to be self-consistent. Obviously it will be better (though not essential) for revision purposes to have been to day 1 before attending day 2.

Who should attend?

The workshops will be suitable for herbal practitioners, nutritionists, botanists, pharmacists and allied subjects, and any researcher with an interest in plant chemistry and/or pharmacology. The workshop will also be very useful to students in all these subjects.

Day 1: Phytochemistry

By the end of the seminar the attendee will:

• Have a detailed knowledge of the nature and properties of primary and secondary plant substances.

• Know some of the key plant metabolic pathways that produce secondary plant substances.

• Be able to evaluate simple chemical identification tests and separation techniques such as chromatography.

• Understand the value and use of more sophisticated techniques such as High-performance thin-layer Chromatography (HPTLC) and High-performance Liquid Chromatography (HPLC).

Day 2 Pharmacology

By the end of the seminar the attendee will:

• Be able to demonstrate a detailed knowledge and critical understanding of the pharmacological effects of the major groups of plant compounds used in their practice.

• Have a detailed knowledge and critical understanding of the mode of action of common medicinal plants, including Schedule 20, restricted and some toxic herbs.

• Be able to critically evaluate the limitations of plant biochemistry as an explanatory model for herb actions.

• Know how to use a range of established techniques to undertake information searches and to be able to evaluate current information on plant biochemistry, pharmacognosy and toxicology.

Preparing for the workshop

There will be a chemistry component to this workshop, but don’t let that put you off joining – It’s really just another language to use to understand the herbs and it will enable you to get a deeper appreciation of modern research into CHM, as well as help you communicate with other herbalists and medics.

For those with rusty chemistry knowledge, Dr Chris Etheridge recommends preparation using this free website:

If you have not studied chemistry since you were 14 and didn’t understand it much then, don’t worry – try these Youtube videos for a more gentle introduction:
