writes I've just done a Google image search on Aloe Vera and the images that came up included varieties which had the broad leaves and ones with long spikes at 90 deg. The image which seems to resemble mine is this one: http://davarree.free.fr/Aloe.Vera.JPG I've also had a look in the book mentioned above for other possibilities to get oxygen at night in my north-facing bedroom - seems as though the snake plant might be the one. Aren't there lots of possibilities? Isn't this to do with crassulacean acid metabolism (because it was first discovered in the crassulas) whereby a great many plants in arid regions have adopted a metabolism that allows them to do their photosynthesis in effect at night, so they can shut down their stomata during the day and avoid losing water?

aloe vera
Can you post either to a link to a site with a picture, or post a pic in altt.binaries.pictures.gardens, of your "Aloe Vera". -- David, just posted two links to pics that look like my aloe vera - here they are again: http://davarree.free.fr/Aloe.Vera.JPG http://laurenharman.tripod.com/portf...mages/aloe.jpg The drawing is very much like mine in that the long spikes at the top bend over and that's what caused it to get top heavy and flop over. The spikes on mine, however, are much more at 180 deg to each other so probably don't give as much counterbalance. The "teenage" one in a south-facing room with lots of light is exactly the same shape so I anticipate having the same problem with that as it gets bigger. Actually, I've just had another look at the teenage one and the later spikes are a bit more evenly spaced so maybe the answer is that more light will stop the 180 deg. angles. |

It's a long, long time since I read about this. The book doesn't go into so much detail. It mentions the aloe, snake plant, orchids and bromeliads as releasing oxygen and absorbing carbon dioxide at night. Although it does feature a crassula, it doesn't mention the same properties for it. The snake plant seemed to be the one most suited to a north-facing room as the others need more light. |

"datsy" wrote in message ... Sounds to me as if your plant is in need of some good light, by the sounds of things the poor devil is having to search for light so is not growing upright and compact. Try putting it somewhere where it can get full light. -- Now this does actually make sense as it's in a north-facing bedroom. Reason for this? Because aloe vera gives off oxygen during the night - apparantly most plants do this during the day - so aloes are recommended as bedroom plants! I'm going to have to forego my oxygen to save my plant! The amount of Oxygen given off by your aloe during the course of the whole night will be less than one small puff of breath, so you won't be losing much. Franz |

Actually it will only do this if it gets enough sunlight during the daytime so you are probably wasting your time growing it in a north facing window. Buy a different plant "~) Here's a book that lists various other options : http://www.mower-magic.co.uk/amazon/...sin=184188121X Yes, I've already got this book - it's very good. Going back to my aloe vera - it looks nothing like the one in this book which has broad "leaves" growing at 90 deg. to each other. Mine has very thin spikes growing at 180 deg. It was labelled as an aloe vera! But none of the pictures I see ever resemble it! That almost certainly means it is some other species of aloe. Aloe vera sells itself to the public instantly so there is a temptation to mislabel. Perhaps your have A. millotii from your rather short description. Regards, -- Martin Brown |

It's a long, long time since I read about this. Yes. Thats the one. Many plants from arid climates have CAM to minimise water loss. They only open the stomata at night. And make exotic photosynthesis intermediates in sunlight completing the cycle at night by grabbing more CO2 and emitting oxygen waste products. However, it does require that they see enough strong sunlight to make a decent amount of growth and oxygen. Otherwise they are budget neutral. Regards, -- Martin Brown |

Datsy, let's do a little sum: Give or take a factor of ten, the amount of Oxygen released in 24 hours will be comparable with the mass of plant material produced in 24 hours. Your aloe would grow less than 1 gm of dry plant matter in a day, so it might be expected to produce less than 1 gm of Oxygen per day. The density of Oxygen is around 1 gm per litre. So your plant will produce something less than 1 litre of Oxygen overnight. That is about one lungful. (All give or take a factor of 10, as I said). You would get much more than 1,000 times as much Oxygen into your room by the simple expedient of sleeping with an open window. Franz |

My main purpose for buying the plant was its use in skin care. Having used commercial aloe vera gel for many years for things like sunburn, insect bites, eczema, etc., it seemed a good idea to be able to use it fresh.

A friend of mine has just been through radiotherapy and she bought a plant to help with skin care after the treatment. In the US some radiotherapy units have aloe vera plants so that patients can use them immediately after treatment. This is to get the record straight as to why I have an aloe vera (or whatever it is - or more to the point, whatever they are, since they're multiplying so rapidly)! |

It *is* worrying if garden centres are advising customers to treat their skin with something that is not beneficial and can even cause harm. I bought mine from a garden centre where they had a number of these plants and they were in fact giving the benefits of aloe vera to a customer in front of me who was suffering from bad eczema. |

aloe vera
On Fri, 6 Aug 2004 18:31:21 +0100, "datsy"
wrote: I've got an aloe vera plant indoors - the type which has the spikes growing at 180 deg. rather than 90 deg. and the spikes are eventually flat rather than upright It had been leaning towards the light, I turned it round and it started growing back. But with a lot of new growth coming through, it got too top heavy and just flopped over today. It's only a hand's width to the growing tip but the new spikes are about 9" inches long. I've put a stick in to support it but it looks a bit silly. Any ideas on how to support it or strengthen it? Thanks! By spikes I presume you mean the leaves. But I'm not sure I understand this 180 and 90 degree bit. Most aloes produce their leaves all round the stem, with one or two exceptions (A. plicatilis comes to mind, but I doubt you have that from the images you gave links for). My SiL calls all aloes 'Aloe vera'! Aloe vera is a stemless aloe. All the leaves grow from the base, forming clumps, and it spreads laterally by side shoots and suckers. What you have is unlikely to be A. vera, but what it actually is, is difficult to say. There are many aloes with stems and with broadly similar appearance. Some have a rambling, scrambling habit where the stems may extend for several feet (A. ciliaris can reach 20ft). If yours is a scrambling aloe, you'll always be having to support it if you want it to grow upright, as that's not it's natural habit. But as others have said already, they need as much light and sun as possible. Whatever it is, it's probably being drawn by the lack of light. Incidentally, a quick calculation suggests your bedroom already contains roughly somewhere between 5 and 10 kilograms of oxygen. The amount produced overnight by an aloe (or any plant for that matter) would be trivial in comparison, as Franz has pointed out. -- Chris E-mail: christopher[dot]hogg[at]virgin[dot]net |

Why don't you get a medicament for your condition, prepared to a known concentration, with a determined dosage rate, on prescription from your doctor? All this messing about with raw plant material is either pointless or dangerous. Franz |
