Archive Newsletter 3 Petitgrain Oils April 2012

Archive Newsletter 3 April 2012
Greetings from autumnal New Zealand- it has been great having some extended sunshine after our dismal summer. The biggest excitement at aromatic adventures HQ has been the planting of my 14 precious Rosa damascena bushes, finally after a year being pot bound. These will be used exclusively for distillation for hydrosol and I will update on their progress in the blog. I have also just started planting a hedge of Osmanthus fragrans, also destined for the still in spring.
As promised this newsletter  is all about the wonderful world of petitgrain essential oils. Petitgrain literally means ‘small fruit’, and is generally used to describe the essential oil obtained from the leaves and twigs from the bitter orange tree. All petitgrain oils are obtained by steam distillation of the leaves and twiglets from varieties of citrus trees from the rutaceae family. Often they are produced after fruit harvesting has finished and the trees have routine pruning. There are several types of ‘Petitgrain’ oils available. Most are only rarely offered on specialist aromatherapy price lists. If you do get the opportunity though, they are worth the investment for adding some unusual oils to your collection to use for blending. There are no known documented safety concerns for any of the petitgrain oils and can be used in usual aromatherapy concentrations. There are no blending ‘rules’ with the petitgrain oils and all blend well with each other and other citrus oils as well as florals and woods. I haven’t had much success with using herb oils in the blends. It would be great to hear of any successes or experiments you have had with using these oils. Another unusual oil is a co- distilltion of petitgrain and neroli which makes for a delicious aromaThere isn’t space to put all the references for the information supplied here however if you are interested please email me wendy@doctorwendy.net.  If you know of any aromatic businesses who would like to advertise with us or have an event to promote then please let me know! I am repeating my Win Stuff for May- we had lots of new sign ups -but not sure if or who recommended them- so tell your friedns and if they mention you you will both go in the draw to win- see the side bar!
Don't forget the greatest Aromatic Event of 2012 is  Botanica2012 in Dublin- have you booked yet?? It will be a wonderful time to connect and learn and share with all sorts of people from around the world. Next newsletter i am presenting information on Rosalina and Nerolina Essential oils.

History
Kaffir lime leaves are widely used in Asian cooking, especially in coconut based dishes. The rind of the fruit is sometimes used in cooking as well. Little documented use of the essential oil. The juice is widely used medicinally as an expectorant, for gum disease and as a digestive.
The origins of the naming of plant are controversial as the word ‘kaffir’ has been used as a derogatory term for Black people and has its origins in the Arabic word ‘kafir’ which means ‘infidel’ or non muslim. Other languages have variations meaning terms such as barbarian or backward.
Orange Petitgrain
Sweet orange C. sinensis
Main oil countries
Italy
Aroma and key constituents
Sharp, sweet , woody. over 100 constituents identified. They can vary 
 on the actual cultivar with sabinene being the most prominent at >38%. others include linalool (>6%); aldehydes (< 6%) and alcohols (12%)
Therapeutic uses
Nil documented-analysis suggests antiseptic (linalool), gentle expectorant, soothing and balancing (terpenes), gentle anti- inflammatory (sesquiterpenes).
Aromatherapy details
This oil is not generally available as it is considered to not have any commercial value. Despite this it has been widely analysed and different subspecies compared. When it is produced it appears to mainly be used as an adulterant for the more expensive Petitgrain brigadier. We think this is a shame as it would certainly be an interesting oil to add to a blending repertoire. Based on the constituents it would be antiseptic, toning and have a gentle anti inflammatory action

Lemon Verbena Harvest & Distillation December 2013

Aloysia triphlla (Lemon verbena) in flower Lemon verbena (Lippia citriodora) or Aloysia triphylla is a precious essential oil which has a low yield and is quite hard to come by the genuine oil. Details as to its origins and habitat can be found here on Wikipedia.  It is believed many so called lemon verbena oils on the market are heavily adulterated with lemon thyme, Litsea cubeba (May chang) or synthetic citral. Previously I have used lemon verbena hydrosol my friend produced on his lavender farm ( www.lavender-impressions.co.nz ), with only a tiny amount of oil obtained. Most of his lemon verbena leaves are destined to be dried and sold as a herbal tea. On the 29 December 2013 I was able to take part in the harvest and distillation of his organic lemon verbena. The key difference this year is that it is the flowers and leaves which are being distilled, not just the leaves. Leaf only essential oil can produce a high (up to 35% citral) content which, being an aldehyde may irri

Geranium Distillation for Hydrosol

This is a the first run of my small scale back yard set up on various geraniums distilled for hydrosol, using a pump to reticulate water through the condenser to save water. It means I do not have to stay close by every second for two or more hours. (I am still in the vicinity though in case of mishaps!) Day 1: Harvest of lemon geranium ( Pelargonium crispum ) this morning, stripped leaves from branches (approx 500gm plant material) and added to 3 litres of commercially distilled lemon geranium hydrosol so I get double the benefit. I don't extract any essential oil out of it. https://youtu.be/LFVPV6WHCIg . I achieved about 600 ml good quality hydrosol after 3 hours on the hot plate. (leaf 1 in picture below) Day 2: First up is rose geranium ( Pelargonium graveloans var. roseum ) with pure water (leaf 2 in picture below). Hydrosol appeared very quickly and prolifically, obtaining 200 ml within first 20 minutes of the distillation. This was distilled for about two hours  and

Harakeke-NZ Flax-An iconic Plant

Harakeke, Phormium tenax , isn't exactly an aromatic plant, but it does have plenty of healing properties. Nothing screams out 'New Zealand' more than an image of our native flax in flower! Further background about the plant can be found here Currently I am surrounded by a variety of them in my garden- planted as short a time as two years ago and they all have swung into a tremendous flowering action, some with spikes almost 3 metres tall. Like a triffid the spikes seem to appear almost over night.  My plants have a number of very practical uses- firstly to assist with drainage of a heavy clay soil with a high water table; secondly for shelter and privacy; thridly to attract more nativve birds (like our TUI ) who feast of the nectar; and lastly (but by no means least) I collect the seeds and use as a co distillation with lavender hydrosol to incorporate into products.   The uses of flax historically is entrenched in Maori culture and history, and early Maori could not be
