"Or does one antagonise the other and cancel the benefits?"
I look at the current literature suggests that the major compounds in apricot kernels , amygdalin or laetrile, do not have major interactions with CBD. However, there are a fair amount of sources that state amygdalin (often used as an alternative to chemotherapy) converts into cyanide and is toxic. The FDA has a current charges/ convictions against a laetrile distributor in the US After reviewing the information available, I wouldn’t recommend ingesting/ consuming apricot kernels. I hope this helps.
