These two are the bare basics, and must-haves for people first starting out in Hoodoo, be it for a dabbler or a person serious in magic.
With just these two, even a hoodoo root worker should be able to get by with no trouble at all. (As long as no cursing or domination work is involved.)
7-11 Holy oil is a biblical oil, mentioned in Exodus. It is also known as the traditional hoodoo oil "High Altar Oil." Its uses are obvious, that for prayer, devotion and blessings. For God, and for giving thanks to Saints and petitioning them. It has a very gentle resonance, and can be used for healing, tranquility and protection.
Special Oil #20 is mostly as it says on its label. It's a very good all-rounder, but mostly in love, luck and money. Because it is an all-rounder some people think it is weak. No, I assure you not at all. It is very strong, just not precise or specialised like other oils.
I find it difficult to put into words, but it has a very strong vibration or presence. It feels "big", "bulky" with a punch. (I'm abit of an empath, so I can feel it.) The best description I can come up with is that it just feels very powerful, and very lucky. Hence it can be used in protection and power spells, but it works differently from say, Power Oil or Protection Oil, but still getting the job done.
I'm sure you all know what I mean.
