thank you for all the information.
I don't have fresh SJW. only dried herb and oil. I guess if I put 1-2 drops in 1 l of water or boil/soak some dried herb it wouldn't be too much.
No, doesn't sound like too much, but I have done very little preparation of herbs from raw form to anything else.
I looked up the LD50 of two of the main constituents of SJW, obviously in isolated extract form. Can't link to the books themselves, sorry:
Quote:From what I've read, boiling is generally to be avoided, in some cases you only simmer below boiling for a varying time depending on the herb; boiling for more than two to five minutes at a maximum is very seldom done for any herb. If you do boil the herb you'd need to be sure to lid it properly so you don't lose any essential oils in the steam but that would be necessary even if you're just simmering it.
A dose of SJW for a goat-size animal is one handful of herb to two pints of water (according to one old herbal book I've got which thus far I have found quite reliable). This is for internal use.
External use is made stronger, two handfuls to two pints.
Oil is prepared by using two finely cut handfuls of flowers, immersed in a half pint bottle of olive oil, placed in a pan of cold water which is then slowly brought to a high temperature but kept below boiling point, simmered for one hour, then removed from the pan and the flowers left to steep in the oil for a further few hours before being used.
Ointment was made by pounding the flowers to pulp, mixed with chamomile flowers, (also pounded/macerated), two parts SJW to one part chamomile, then added to melted lanolin at a ratio of 50:50 herbs/lanolin.
With St John's Wort, the fresh flowers steeped in olive oil were used for all manner of wounds and skin problems.
You could look into making an essence or tincture too if you're worried about internal use. There's a variety of ways to do either, but they would be for external use since they're made via utilizing surgical spirit or vinegar for preservative, however if you're worried about toxicity levels this could be a safer way to apply... The research I linked to before does mention external application as well, so it could work.
Tinctures are made by taking about two ounces dried herb, put it in a large pot or jar, add one quart alcohol (cheap surgical spirit or vinegar can be used), let it stand for two weeks, then it's ready to use. Obviously needs storing in a dark place, and well lidded due to high evaporative properties.
Boiling it could be detrimental to the active compounds; I know it is with some herbs but others are fine to boil.
before I got chickens I did a lot of research and found that garlic and onion are not good for chickens. but later I found out that people do give them so I tried. my chickens love both and not only they have never had any problem but they are getting well sooner with garlic and onion (I live in greece where it is very hot, windy with strong storms so there are plenty of viruses). my vet does not approve acv either. when I mentioned iodine he got mad and told me that iodine had been used by our grannies who didn't know what to do. but when all of my chickens survived dry and wet pox thanks to iodine he was surprised and didn't say a word. at least he started to pay attention when I say what I give my chickens and is willing to learn.
Odd that a medical professional would get mad about iodine which is still so widely used in modern medicine for its well documented properties! :/ 'Got mad' --- yikes! But if he's willing to learn that is great.
Best wishes.
I have just found I have what appears to be a classical case of Marek's in my flock, in a chick bred from a new rooster.
I brought this new rooster despite knowing he's of a breed known to be weak against most things (he was really only brought in for company for my damaged and tiny old pet hen)... He's a Japanese bantam. Asides from Seramas (which I can't get here), size-wise he's the only mate fit for such a damaged hen; I am semi-seriously considering getting her x-rayed when she dies to count the fractures and breaks all throughout her skeleton. (For those not familiar with her history, a feral dog jumped up and down on her). She's got a mosaic of a skeleton now.
One of his sons has developed the classical split-leg paralysis and he's right in the most at risk age group, and his eyes have greened a bit. Before, for a few weeks, I had noticed the classic wing weakness, both wings drooping so the primaries were splayed out (rather than the whole wing sagging, it's just the extremities).
If he dies I'll get it confirmed or discounted as to what it was but right now I am treating as though for Marek's.
I'm going to start with turmeric+oil+black pepper mix ('golden paste' as some vets recommend for a huge variety of problems) and when I have bought some SJW I'll be using that too... Or maybe I will use the fresh plants on the property. It certainly does look like Marek's but time will tell. And testing, if he dies.
I also have one of my oldest hens from a line almost completely prone to ALV, who is now showing the same symptoms the others did before they died. Almost her entire female family tree died of ALV, I culled it out quite aggressively, but she was kept on for eggs because she didn't go down around the two year mark like they did so I thought her clear. Maybe not, after all. She wasn't used for breeding anyway but may provide some education.
I gave her a dose of turmeric and she's perked up and is acting normal, but time will tell, ALV is notorious for relapses from normal behavior. I thought she'd be dead in the morning, she went down so suddenly and hard. Time will tell.
