Welcome @jada1!
I know there are a few folks here who use Mugwort somewhat regularly in their Crafts, so I’ll let their words and experiences from the following discussions help guide you:
→ Mugwort is not a gentle plant and it is not for everyone!
→ Mugwort Questions
Also, @Silverbear shared a fantastic overview video of Mugwort with a lot of helpful advice:
I’ve had mugwort baths before and really enjoyed them 
and external use seems to be quite safe but, as others have mentioned in the resources above, ingesting it in any amount should be done with caution.
For Mugwort Dosing, WebMD says the following:
The appropriate dose of mugwort depends on several factors such as the user’s age, health, and several other conditions. At this time there is not enough scientific information to determine an appropriate range of doses for mugwort. Keep in mind that natural products are not always necessarily safe and dosages can be important. Be sure to follow relevant directions on product labels and consult your pharmacist or physician or other healthcare professional before using.
From WebMD: Mugwort
As with any herb, it may interact negatively with other medications or herbs you are taking. If you can find a local herbalist or apothecary that you trust, I’d suggest bringing a copy of your personal medical details/history and consulting with them if Mugwort is safe for you, and if so, the exact limitations and amounts your body can safely handle.
Happy spellwork and enjoy your new Mugwort, Jada- Blessed be!
