Working With Scott Cunningham's Herbal Reference
The Cunninghams Encyclopedia Of Magical Herbs Llewellyns Sourcebook Series Scott Cunningham is essentially a plant-by-plant reference catalog for anyone doing folk magic or herbal craft work. It covers over five hundred entries, each with a brief overview, magical correspondences, and suggested uses. The layout is consistent: plant name, pronunciation, family, part used, planetary associations, and a paragraph or two on magical properties. I keep a copy on my workbench because I reach for it when I need a quick lookup on something like vervain or comfrey. The entries are straightforward. Each one gives you the basic correspondences and some practical application notes. That is the entire value proposition. It is not a scholarly text with citations. It is a working grimoire-style reference compiled from Cunningham's own practice and the wider folk magic tradition he drew from. One thing beginners consistently get wrong is treating the planetary and elemental attributions as fixed rules rather than flexible starting points. Cunningham himself noted that correspondences vary by tradition, region, and even the individual practitioner. The book lists what he found most useful. It does not claim to be the final word. If you are doing a working and the herb you want is listed under Venus but your personal intuition says otherwise, trust the intuition. The book is a tool, not a constraint.
I ran into a specific problem last year when I was formulating a protection blend and needed to cross-reference ash with several other resins. The encyclopedia entry for ash covers the general correspondences but does not go into the variation between mountain ash and European ash. These are botanically different species with slightly different traditional uses. I had to supplement the entry with a second source to confirm the European variety for binding spells versus the mountain ash for warding. The workaround was simply keeping a basic botany field guide nearby to clarify which species was which when the entry was ambiguous. It took maybe five minutes and saved me from using the wrong material in a working that was already scheduled. The organization is alphabetical, which makes sense for a reference book but means you cannot browse thematically without jumping around. If you are looking for all the herbs associated with prosperity, you need to scan or search. There is no index of correspondences. Some people photocopied the tables and made their own cross-reference sheets. That is probably still the most efficient workaround if you use the book regularly. The entries are concise. Some are one paragraph. A few run to half a page. This works well when you already know roughly what you are looking for. It is less helpful when you are trying to learn an herb in depth before your first working. In that case, you would need to follow up with more detailed sources on the botanical and historical background.
There are also limitations you should be aware of. The correspondences reflect folk magic conventions, not academic herbalism. If you are using the book alongside apothecary-grade herbal practice, be clear about which framework you are operating in. Mixing the two without that distinction can lead to confusion about dosages, preparation methods, and safety. The book does not cover toxicity or drug interactions. That is not its purpose. You need a separate medical herbalism reference for that. Another common issue is assuming every herb listed is equally accessible. Some entries cover wild-harvested plants that may be protected or difficult to find in certain regions. The entry for coltsfoot, for example, notes its traditional uses but does not address regional availability or sustainable foraging practices. If you are sourcing locally, check your regional guidelines before collecting anything from the wild. The edition matters. The original Llewellyn publication has been reprinted multiple times. Later printings may have minor corrections or expanded entries. The core content remains the same across versions. If you are buying used, any printing will serve the same purpose. The references and correspondences do not change significantly between editions.
Get the Full Details

For someone just starting out, this book gives you a reliable foundation. The entries are accurate to the folk magic tradition and easy to read. It is not exhaustive. It does not replace a full herb Lore reference or a medical herbal text. But as a quick lookup during ritual planning or spell formulation, it does exactly what it promises. You open to the page, read the entry, and move forward with the working. I have found the most useful applications are in the planning phase. Before I begin a new project, I flip through the relevant entries to refresh my memory on correspondences and check for any traditional cautions. It usually takes five to ten minutes and helps me avoid oversights that would otherwise show up later in the process.
