I tried the 2.5% CBD oil, i have tinnitus and many other conditions, Why did i imagine it could help releive or remedy the tinnitus? because when you are suffering you will try things, so i threw £20 at it, did nothing for me , i have also done some research regarding studies on tinnitus and it's possible relation to the CB1 and CB2 receptors in the human brain.... PLUS it is possible that the tinnitus i experience is related to epileptic conditions ..... my experience is that THC does NOT remedy OR increase tinnitus in my case, nor did CBD..... i am VERY experienced with taking THC oils and making THC oils for medical use ..... 10 years ago i bought high CBD seeds, grew them out and tried the medicine, it did not help with the conditions i had then either..... my understanding is that CBD is excellent medicine for epilepsy, but other conditions it is a very weak medicine.... people started to think they could 'cheat' and use CBD to cure cancer the same way THC can, but that is only because they are obsessed with the idea that THC must be avoided because prohibitionists consider it 'fun' .... those same prohibitionists would rather thier own family die in pain that use THC to cure them and thus admit that people like me were right. Is this CBD oil any good? i didn't find it helpful at all, i suspect that CBD is very weak medicine for most conditions except epilepsy. i bought the george botanicals oil because i thought "at least they produce it themselves, rather than simply buy it from china-grown hemp and stick a label on it" , plus they do claim to have labs and test thier product..... i know about 10 years ago when the CBD craze/goldrush/scam exploded the FDA in america tested a random 10 products, oil, vape, balms and they found that NONE of the products sampled contained ANY CBD.... this si why i went with george, at least they have labs and fields of plants so a better gamble than buying from someone who simply rebrands untested china hemp oil
