Co Distillations with lemon Geranium parts 1 and 2

I use lemon geranium hydrosol, commercially produced by Lavender Impressions in a lot of my skin care products. For a few very special products I use a co distillation made of out Rosa damascena flowers which I grow organically and these are co distilled with the lemon geranium hydrosol as the base. I produce so few of the flowers at the moment so I dry the flowers until I have enough to use.

I downsized from my column alembic still (where the plant material is encased in a metal basket and not immersed in the water) to a smaller still where it is in the water. This was my first distillation using plant material this way. I think aromatically the steam distilled has a nicer aroma, softer and fresher and I feel the colour of the distillate is clearer. I have found that some plant material ends up in the condenser so next time I will do smaller volumes and see what happens. I am going to do redistill the left over liquid (not distillate) and see what I get.

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
