Borage seeds do indeed contain PAs, but the borage oil derived from them isn't generally a problem as it usually tests negative.
If the oil is actually certified PA free then it's proven to contain less than 20 parts per billion, as minute traces of PAs below that amount can't be detected in any test. So it's possible that borage oil may always have an extremely tiny amount of PAs, but there's no way to prove this one way or the other.
As for long term use, I would say anything up to 6 months definitely shouldn't be considered a long period of time with any herb or any herbal formulation, but over 6 months could be regarded as long term.
