Lovage is in the celery/carrot family. Most of the plants in that family is poisonous(
medicinal at the right dosage). They are good as culinary herbs/tinctures/medicinal. I would use them. Garlic which is another herb is known to affect the blood and heart too. The mint/thyme family similarly are very bio-active. But you know your body best. I know some people who are allergic to even pear even though I can eat a ton of it.
Iterations are fine, we don't have to be perfect
