CBD has been proven to be an anti-inflammatory which can help a number of issues in the body.
It is also an anti psychotic and an anti anxiety
The issue with CBD is it has a bell curve chart for effectiveness. If used solo (cbd) without THC (the 'high' in cannabis') the body can get very use to it. Also, certain % is needed to have good effects.. I think it's around 30%
CBD is also very expensive due to it being a lengthy process to extract from the hemp / cannabis plant.
Holland and Barrents jumped on this band waggon and started becoming "one of" the first UK companies to promote cannabis oil. However they are cons and should not be trusted. You pay around £30 for 5% CBD which is appalling in a 30ml bottle.
There are far better ways to get CBD and from trusted companies also.
You can buy a whole gram of pure CBD isolate for £30... so 5% of 30cl is literally barmy.
The best way to get as much as the CBD as possible is to vape it... Eating the CBD only gives you 60 ish % ...
however you probably don't want to vape it.
A company i really really recomend is either :
CBD brothers (UK, they also give out free samples for those in need, but you need to catch them at the right time of the month)
CBDistillery (cali company)
CBDstillery has the exsperience, funds, and "audience" large enough to really be going places in development of the product and understanding what/how/where it helps.
I would recommend trying this oil at first.. Then going from there.
