Jamika asks:

Dear Sean- Can you advise an herb for really really really bad menstrual cramps?

Yes I can.
In the herbal world cramping is considered spasms. What you want to control cramping is naturally an anti-spasmodic. This would be similar to formulas that one would use for nervousness, shock, as well as cramping.

To name 1 herb for this condition I would definitely go with one that is anti-spasmodic and has affinity for the Female Reproductive System.
Black Haw is the most powerful single herb for this. A possible substitution is Cramp Bark (for cost, availability, etc…)
A tincture would work best here. Take about 20 drops 2-3 times daily or as needed.

General herbs many may have around or easier availability would be Skullcap, Lobelia, and Valerian.

Jamika, hope things go well for you. Should you get me more info we can come up with a bit better of a formula for you next time.

Perhaps to make it easy you can just buy a formula straight from online that can help very much in this! Try these PMS & Cramps forumlas from Dimmak Herbs
