What do the eyes reveal?

Bullet 3. Practical Iridology

Iridology for Herbal and Natural Health Consulting

It has been said that the eyes are the windows of the soul, but iridology, the study of analyzing the eyes, suggests the eyes primarily tell us about our constitution-—our inherent genetic strengths and weaknesses. In other words, the iris tells us what nature gave us to work with.

The various patterns, signs and markings in the eye reveal inherent strengths and weakness in the different glands, organs and tissues of the body. This tells us where our body’s are most likely to break down when subjected to stress, nutritional deficiency or a toxic environment. This can not only provide clues about how to help the body heal from disease, it can also help us develop a lifestyle that prevents disease from ever gaining a foothold.

Personality traits are linked into the genetic make-up of our constitution as well, and the iris also tells us about these traits. The iris reveals our dominant learning mode (auditory, visual or kinestheic) and our primary way of process information. It also tells us whether we are predominant introverted or extroverted, how much stress we can handle (physically or emotionally) and about some of our genetic talents (and hangups).

In these videos you’ll discover these and other treasures the eye reveals, while learning to read the iris in an easy and systematic manner. Plus, you’ll gain practical understanding in how to use the iris to help you select appropriate supplements, diet and lifestyle changes based on what you see.

  • The 84 page manual Practical Iridology with color iris photos.
  • 4 DVDs

Bullet 6. Herbal Preparations and Applications

    • How do you convert that capsulated formula into a tea or glycerite so a small child can take it?
    • How do you get herbs into someone who is having a difficult time swallowing?
    • What’s the difference between an alcohol tincture, a standardized extract and a glycerite?

    These are the kinds of questions answered by Herbal Preparations and Applications.

    Understanding the difference between the various herbal preparations (capsules, tablets, tinctures, oils, etc.) and the advantages and disadvantages of each is one of the factors that distinguishes a skilled herbalist from a beginner. Knowing creative ways to get the herbs where they are needed (poultices, baths, gargles, eyewashes, linaments, enemas, douches, etc.) is another. This knowledge provides an herbalist with flexibilty and options to meet every need.

    In these videos, professional herbalist Steven Horne takes you into the kitchen where he “cooks up” a variety of herbal recipes. You’ll learn about how herbs work in combination, how formulas are designed, how to understand different potencies in tictures (1:1, 2:1, etc.) and much more. If you are a “do-it-yourself” kind of person, you’ll find his easy-to-follow information will have you “cooking up” your own herbal “brews” in no time. Even if you’re not a “do-it-yourselfer,” and rely primary on commercial herb products, the information contained in these videos will help you become a better herbalist by learning how to use your products more effectively.

    There are many ways that herbs can be prepared and administered in addition to taking them in capsules. This course teaches the various application methods and instructions for preparation of plant medicines both internally and externally, including making infusions, decoctions, tinctures, glycerites, syrups, boluses, and more. It also covers the many ways to administer herbs, including enemas, baths, poultices, compresses, fomentations, and so forth. It explains how different preparations can alter, diminish or enhance an herb’s particular energetics. Learn all the different ways to prepare and use your herbal remedies.
