INSUFFICIENT RELIABLE EVIDENCE to RATE

• Allergic rhinitis (hay fever). Although there has been interest in using oral skullcap for allergic rhinitis (hay fever), there is insufficient reliable information about the clinical effects of skullcap for this purpose.
• Anxiety. It is unclear if oral skullcap is beneficial for reducing symptoms of anxiety. Details: Preliminary clinical research shows that healthy people who take a single dose of freeze-dried skullcap extract 100-350 mg feel more relaxed when compared to baseline. This effect appears to last for about 2 hours (12216). However, other preliminary clinical research in healthy patients shows that taking freeze-dried skullcap (Skullcap, Eclectic Institute) 350 mg three times daily for 2 weeks does not reduce anxiety scores when compared with placebo (91690). Because these were short-term studies in healthy patients, it's unclear if skullcap is beneficial in anxiety disorders or if extended use is beneficial.
• Atherosclerosis. Although there has been interest in using oral skullcap for atherosclerosis, there is insufficient reliable information about the clinical effects of skullcap for this purpose.
• Contact dermatitis. Although there has been interest in using oral skullcap for contact dermatitis, there is insufficient reliable information about the clinical effects of skullcap for this purpose.

General ...There is currently a limited amount of information available on the adverse effects of skullcap.
Most Common Adverse Effects:
Orally: Cognitive impairment, digestive disturbances, sedation.

Gastrointestinal ...Orally, mild digestive disturbances were reported in around 9% of patients taking skullcap 350 mg three times daily for 2 weeks (91690).

Hepatic ...There are four reports of hepatotoxicity associated with products thought to contain skullcap. However, it is uncertain whether the products actually contained skullcap. It is thought that the products might have been contaminated with an adulterant such as germander (515), which is known to cause liver damage.

Neurologic/CNS ...A single skullcap extract dose of 100 mg does not seem to have adverse CNS effects. However, a higher dose of 200 mg might cause sedation and cognitive impairment (12216). One patient taking skullcap 350 mg three times daily for 2 weeks reported vivid dreams (91690). It is unclear if this event was associated with skullcap.
