I've not been on any Eve Taylor courses, but it's a shame more courses don't have an emphasis on skin analysis. I'm always suprised how little some therapists know about skin conditions & causes of them. So many treat the visual evidence on the surface without understanding what's going on underneath to cause them in the first place, and if you don't address the underlying processes you have no hope of 'treating' a skin condition.
It seems a lot of colleges are in the dark ages when it comes to their knowledge of the skin; if indeed they even teach the students about the skin at all.
On the subject of 'flower waters', are you talking about 'hydrolats'? If so, there are some fantastic books on the use of these as an adjunct to aromatherapy. The following uses applies only to those without preservatives:
They make excellent washes for eczema, wounds & burns, as well as being good for gargles, nasal sprays, skin sprays & as a ******. High quality hydrolats also make good eyewashes (Roman Chamomile is excellent in this way for inflamed eyes, and on a compress is great for itchy hayfever eyes). You can also take high-quality hydrolats internally (like rosewater) for absorption via the digestive tract (such as a teaspoon poured into another drink - up to 3 teaspoons a day is considered 'safe') & via the rectum as an enema. Externally you can add 50ml to a bath for it's effect on the skin, or soak gauze in the water to make a compress.
