I already used for some time and it is really convenient for its list by name of "disease" flatulence, cramps, cystitis, insomnia, migraines, stretch marks (pregnant or not) etc ... (in addition to the description of essential oils) it offers every time "reflex" with the use of a single essential oil, and more comprehensive formulas. it also lists the HE used by pregnant women (even during the 1st quarter) specify when it can be used for baby or children, but we must also think of reading the first pages which specifies modes administration, for whom, how ... well I recommend it to everyone!
