Distance Learning Study for Practical Skills and a Career in Professional Herb Production
'“This is beyond what you would learn in a Trade Certificate in Horticulture. It teaches you everything a tradesman would learn about plant culture; and more science, plus more plant identification than what an average tradesperson whould know” - John Mason Dip.Hort.Sc., Cert.Supn, FIOH, FPLA, Professional Horticulturist for over 40 years, Garden Author and educator
“Learn to grow plants first! This may sound simple but in reality a herb is a plant like any other, and to be truly successful in this field you will need the general horticultural knowledge offered through this terrific course. The second half of the course focuses on the diverse aspects of herb growing from medicine to farming. A wonderful course in an exciting field.” - Adriana Fraser Cert.Hort., Cert.Child Care, Adv.Cert.App.Mgt., Cert 1V Assessment and Training, Adv.Dip.Hort, LC Tutor.

Extract from Course Notes:
HERB OIL PREPARATION
DISTILLATION
Herb oils are best and most commonly extracted by distillation, a process which is probably beyond most home herb gardeners. Distillation involves boiling a solution of the herb so that the oil vaporises with steam. As the vapour cools, the steam (ie: water gas) and the oil vapour will turn into liquid at different temperatures. By collecting the oil when it turns back into liquid but not collecting the steam, the two can be separated and the herb oil extracted.
Pure herb oils prepared by distillation can be purchased from craft shops or some herb nurseries.
USING NON AROMATIC OILS
A simpler way to create herb oils is by using non aromatic oils (eg: Olive oil or Safflower oil). These are oils that have no real odour.
Herbs can be mixed with non aromatic oils and allowed to stand for a period of weeks (or more).
The oils in the herb will to some degree penetrate the non aromatic oil giving a mixture of non aromatic oil and the herb's scents/flavour. This type of oil is weaker than that extracted by distillation, but it can still be used in much the same way as the pure herb oil can.
OTHER METHODS
1. Place petals from scented flowers such as Jasmine or Rose in a clean ceramic container and pour water over the top. After some weeks or months oil will appear as a filmy scum on the surface of the water. You can then use a piece of cotton wool to carefully absorb the oilfrom the surface of the water. The oil can then be squeezed out of the cotton wool. This is a delicate procedure which will work, but is tedious and only yeilds small quantities of oil. Store in small glass vials.
2. To extract oils from fragrant woods such as cedar, sandlewood, sassafras, camphor laurel etc. Reduce the wood to shavings using a wood plane for tough woods, or garden shredder for softer woods. From there extract the oil using one of the methods outlined above.
Exams: There are four exams for the course; one after lesson 7, another after lesson 15; a third after lesson 22 and the final at the conclusion of the course.

Studies prove, time and again, that college-educated workers earn more than those with only a high school qualification. College graduates often enjoy additional benefits, including greater job opportunities and promotions. Though the proof for greater earning potential exists, some might wonder whether the cost of the education warrants the overall expense in the long run.
College Graduate vs. Non-Graduate Earnings
The National Centre for Education Statistics (NCES) analyses employee earnings data biennially, according to education level. Findings indicate that workers with a qualification earn significantly more than those without. Since the mid-1980s, education has played a large part in potential wages, with bachelor's degree holders taking home an average of 66% more than those with only a high school diploma do. While college-educated workers' wages have increased over the past two decades, those with only a high school education have seen decreases in annual salaries in the same time period (nces.ed.gov).
