The present invention relates to the use of a therapeutically effective amount of cannabidiolic acid (CBDA) in the treatment of epilepsy. In one embodiment the CBDA is used in the treatment of generalised seizures, preferably tonic-clonic seizures. Preferably the CBDA used is in the form of a botanical drug substance in which the CBDA content is greater than 60%, and most preferably, it is a highly purified extract of cannabis such that the CBDA is present at greater than 95%, through 96% and 97% to most preferably, greater than 98% of the total extract (w/w) and the other components of the extract are characterised. In particular the cannabinoids tetrahydrocannabinol (THC) or tetrahydrocannabinol acid (THCA) have been substantially removed. Alternatively, the CBDA may be synthetically produced.
