Human Studies A Home Use Test (HUT) performed in 2005 among a target group of 61 men and women using Seditol for two weeks yielded very positive results.[1] Seventy-four percent of respondents used the product according to the directions: Take seven or more capsules during the two-week test period. Of these respondents:

  • » 83% said Seditol helped them relax*
  • » 91% said Seditol helped reduce fatigue due to lack of sleep*
  • » 91% said Seditol helped ensure a good night’s sleep*
  • » 82% said Seditol is an essential item to have on hand*


An open-label, single-center, observational survey that included 295 people (ages 18-87) with sleep difficulties was performed to obtain a subjective evaluation of the tolerability and effectiveness of Seditol.[2] Self-reported sleep difficulties included problems falling asleep, multiple wakings, and next-day tiredness due to a lack of sleep. Patients taking at least one 365 mg capsule of Seditol one hour before going to bed every night for at least two weeks experienced the following:

  • » 86% considered Seditol relaxing*
  • » 82.8% said Seditol assisted in a restful sleep*
  • » 82.8% said Seditol was effective in reducing fatigue due to lack of sleep*
  • » No significant adverse events
Seditol (known as SEDITOL®) is a blend of a patented extract of Magnolia officinalis bark and a proprietary extract of Ziziphus spinosa seed. These herbs have been traditionally used in Asia for qì stagnation, for mild anxiety and nervousness, and to support normal, uninterrupted sleep.*[3-5]


Magnolia officinalis Magnolia bark is rich in a biphenol compound called honokiol and its isomer magnolol. In experimental animal studies, these compounds have been shown to enhance the activity of gamma-aminobutyric acid (GABA) A receptors and GABA binding, which may help the body cope with the neurologic effects emotions can have on behavior and well-being.[4,6] Honokiol, administered by intraperitoneal injection in mice, was shown to promote NREM (non-rapid eye movement) sleep by modulating the benzodiazepine site of the GABA (A) receptor.[5] And, in an experimental animal model of chronic mild stress, a mixture of honokiol and magnolol supported normal levels of 5-hydroxytryptamine (5-HT) and its metabolite 5-hydroxyindoleacetic acid (5-HIAA) in various brain regions. The combination also promoted healthy corticosterone levels and platelet adenylyl cyclase (AC) activity. Researchers suggest that these findings provide a basis for further study into the influence of magnolol and honokiol on the serotonergic system, the HPA (hypothalamic-pituitary-adrenal) axis, and the AC-cAMP pathway in relation to mood and emotional behavior.*[7]

Ziziphus spinosa A primary use of Z spinosa seeds in Traditional Chinese Medicine is to support calmness and help individuals with occasional sleeplessness.[8,9] In an experimental animal model, saponins and flavonoids extracted from the seeds showed a significant relaxing effect and helped prolong sleeping time.[8] To investigate potential mechanisms, researchers tested the influence of spinosin—a flavonoid derived from ziziphus seeds—on pentobarbital-induced sleep in mice. They concluded that it potentiated sleep via a serotonergic mechanism.*[10]

Koetter et al[3] studied the interactions of magnolia and ziziphus extracts with selected central nervous system receptors in a series of assays. Interactions with the adenosine A1 receptor, dopamine transporter and dopamine D5 receptor (antagonist activity), serotonin receptors (5-HT1B and 5-HT6 antagonist activity), and the GABA benzodiazepine receptor were demonstrated. It is suggested that these findings provide some insight into the combined activity of these extracts.*
