I can hear ya knockin, ..and I'll let ya in on that one, but if one is using it medically for a sleep disorder such as insomnia, then the indica would be serving its purpose as a medicine, which is +1 for the movement!! I can agree with both sides of the story. I'll admit, recreational is my main purpose for using, but I do keep my high blood pressure under control with regular use as well, which is just..amazing that it works to that effect. Let me get a round of applause for the Marijuana, its just great!
I don't get over here that often anymore, and I noticed your post. You're the first person I've heard of, other than myself, using cannabis to combat high blood pressure. I don't know how much you've researched this, I have a little and there's not much information on cannabis working on high blood pressure out there. Maybe you've had better luck. I don't know if you're familiar with leafly dot com. They have information (dumbed down, not scientific at all) on most strains along with dispensaries that have registered there. The one thing the following strains that work for me have in common is leafly refers to them as being "relaxing" & "reducing stress". Unfortunately, leafly also refers to the second list of strains that DON'T work for me as being relaxing" & "reducing stress" as well.
Here are the strains that work for me so far, in descending order (and it's almost all indicas or indica dominant hybrids.
Granddaddy Purple
King Kong
Dutch Treat
Indica dominant Blue Dream
Grape Ape
Silver Haze (sativa, go figure)
Ultraviolet
Cannatonic (high CBD)
Stephen Hawking (high CBD)
Here are some that don't work on my blood pressure, again, mostly indicas or indica dominant hybrids.
Cherry Pie
9 lb. hammer
Afghan Kush
Bubba Kush
Grape LA
Jager
I'm pretty sure that either the THC or one of the many terpenes in cannabis is what reduces my blood pressure. The reason is this. Mostly I vape flower. I have a volcano. The thing with the volcano is the temperatures are very accurate. THC begins to vaporize, albeit very slowly, somewhere around 200 F, maybe a little higher. It really vaporizes good around 350-360F. The medicinal compounds (CBD, CBC, CBN, CBG, etc.) vaporize around 410-420F. I have no idea at what temperature the various terpenes vaporize. I typically vape a bag at 360F (good taste) and then a bag at a 420F (not a good taste, but you get the CBD's). The blood pressure lowers at the 360F temperature, so that's how I know it's not a CBD thing.
The other thing I've found that works pretty good is hibiscus flowers. Make tea of it. The loose flower work much better than the hibiscus tea bags. It tastes like shit, so mix a nice tasting tea with it. I steep 1 tbl. of hibiscus flower, 3/4 tbl. of a nice tasting tea (zinger or a lemon works for me) in 3 cups of water over night and then dilute it a little throughout the day.
Sorry about the long post and it isn't my intention to hijack this thread. Go ahead and PM or IM (whatever they call it here) me if you want anymore info.
