Botanical Contraindications,

 Warnings and usage Hazards


A number of botanical species can be hazardous. The majority however, can be used safely, if handled with caution.

 A large number of Botanical species carrying warnings, or contraindications,  only pose a risk if ingested, however, each species must be handled with respect and caution.  Particularly if you are pregnant, nursing or have complex medical issues.

Below is a small list of Botanical's which pose some form of risk, the list is based purely on the current range of dried botanical species within our store and is updated as and when we add a new variety.

We advise that before using herbs for any reason, be that spell craft or healing etc, that you research and understand them fully, to keep not only you, but those around you safe, particularly when crafting natural incense blends.

We cannot take any responsibility for any reactions, or negative effects on your person, or your spell craft. It is down to you as informed, and responsible botanical crafters to ensure that you are fully informed with any herb you use

We cannot recommend enough, the true value of a decent  and well informed comprehensive Magickal Botanical  Encyclopedia or equivalent reference
