2 Module Online Webinar Short Course

It is often the essential oil components of plant medicines that have the valuable effects. These components are however, frequently forgotten. This webinar short course will closely examine the most useful essential oil containing plants and how to get the most from them.

Your presenters are both highly experienced herbalists with specific interests in the aromatic plants.
Chris Hobbs PhD, LAc, AHG is presenting a detailed view of essential oil chemistry and usage with lots of recipes and practical applications. He will also be showing us how to prepare the best extracts and compounds to maximise the effects of essential oils phenolics.
Andrew Pengelly PhD will specifically discuss Australian aromatics. These are highly valuable medicines and he will show us how to use each oil. He will focus on the plant species from which it is distilled, essential oil profile, clinical uses and safety along with sensory descriptions and up to date research findings. In addition, there are sections on clinical formulations as well as insect repellants and treatments. Both presenters will discuss the safety aspects of using plants that contain higher levels of volatile oils.

Some of the clinical applications that Chris and Andrew will discuss are;

  • Infections
    • viral
    • urinary tract
    • head lice
    • fungal
  • Topical
    • insect bites
