How do I know what herbs to use? Always follow the recipe!! If you want to begin making your own, consult either a practiced Herbalist or a good book on Herbalism to help you. NEVER under any circumstances, experiment without first reading up on the herb or speaking to a Herbalist. Herbs can be dangerous and many are poisonous if taken internally. So be careful!! If you have any more questions about this, please email me through the link at the bottom of the page.
