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 ( ), 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. . 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
