Most drug interactions are in the 3A4 enzyme.  You have no problems there. But candesartan is a strong inhibitor of 2D6.  CBD is an inhibitor of 2D6.  So, yes, they will boast each other.  But you have several options. 1) Use CBD as a boaster, and lower you dose of candesartan, 2) take one in the morning, one in the evening; or 3) Irbesarten is a moderate inhibitor of 2D6.  Losartan, Telmisartan, Valsartan and Eprosartan do not used 2D6.
Nabiximols (Sativex), a multiple sclerosis drug made from a combination of TCH and CBD, is approved in the United Kingdom and Canada to treat MS pain. However, researchers think the CBD in the drug may be contributing more with its anti-inflammatory properties than by acting against the pain. Clinical trials of CBD are necessary to determine whether or not it should be used for pain management.
PharmaHemp is another gem of a company to come from tiny, green Slovenia. Their hemp fields are also open air, organic and drop-dead gorgeous. They are based in micro-locations in Eastern Slovenia, the Gorenjska region and Croatia. Areas that traditionally grew cannabis before its prohibition. All these locations continue to grow organically. Founded by Andrej Susnik in 2011, engineer and entrepreneur who has worked in the field of cannabis extraction since 1964, PharmaHemp is a solid European player with the leverage of experience and a great focus on organic production. By using supercritical CO2 extraction, PharmaHemp ensures that all their extracts are full spectrum, i.e. containing not only CBD (cannabidiol), but also other cannabinoids, terpenes, amino acids, essential fatty acids (omega oils), bioflavonoids and many other phytonutrients. Their cutting-edge production facilities are matched with very slick packaging and design.

While this is true to an extent, the simple fact of the matter remains that pure CBD oil with customer-backed qualities is a rarity in the legal hemp marketplace. The vast majority of CBD oil online (even products that are extracted with CO2 technology and "verified" with third-party lab reports), is still subpar in terms of potency, purity, and effectiveness.
CannabiGold’s unique selling point is not its oil, however, but its method of application. A common customer issue is droppers leaking because, when the highly viscous oil gets in the rim of a conventional dropper, it is not easy to close the bottle tightly anymore. By listening to their customers and conducting research and testing in their state-of-the-art facilities, the R&D team at CannabiGold developed a precise dropper technology that would allow 10g of CBD oil to be delivered in 400 micro drops, one at a time.
