Many plants are highly toxic and can be dangerous.
Before herbs are used as a treatment, know what you are doing and the history of the herb you are using. Plants can look very similar and common names are ofter misleading-there is a danger of mistaking one herb for another. Before collecting a herb, ensure that it has been correctly identified and do not interchange similar species for a particular purpose, as they may not have the same properties. It is also essential to use only the part specified, usually the leaf, stem, flower or seed and occasionally root. Some plants classified as herbs are highly poisonous in any form or quantity.
