This is not medical advice and should not be taken as such , I am posting this for information and educational purposes only. If in doubt don’t please know your plants before using them.
There are many plants that are poisonous that get mistaken for Scutellaria and are sometimes contaminants in supplements containing Skullcap. Two of the most common that can be mistaken for Skullcap that are poisonous are Downy Skullcap (scutellaria icana) and Germander which is in the Teucrium family.
The ones with the most health benefits in the order of effectiveness are Sculletaria Racemosa, Sculletaria Biacalensis, and the one with the best sedative effects is Sculletaria Lateriflore.
They contain biacalein which I have seen miss spelled as biacalin in some studies. It has amazing healing abilities. S Racemosa has the highest levels of biacelain. It has been shown to be very effective against cancer with little side effects. One of the problems I had with Skullcap was that it healed my nerves and improved my blood circulations so fast that all heck broke loose. The best way I can describe it is when you sleep on your arm and it goes to sleep. As the blood flow returns you experience muscle spasms and major tingling. That happened to me for about three days when I started taking it and then I started to feel much much better. I was surprised at how fast it was healing me. I used Sculletaria Racemosa.
Biacalein has been shown to be effective against liver fibrosis and correct metabolic disorders.
Skullcap helps with asthma and COPD.
It has antibacterial and anti inflammatory effects which helps prevent periodontal disease.
Effective against various types of cancer.
This would also help interstitial cystitis because this is something cancer patients and those with interstitial cystitis have in common.

Reduces inflammation and the way it does it would be very beneficial for those with interstitial cystitis.
