Does mastic improve Crohn's symptoms?

Mastic from Wikipedia
"... a resin obtained from the mastic tree (Pistacia lentiscus). In pharmacies and Nature shops it is called "arabic gum" (not to be confused with gum arabic) and "Yemen gum". In Greece it is known as the "tears of Chios," being traditionally produced on that Greek island, and, like other natural resins is produced in "tears" or droplets. Originally liquid, it is sun-dried into drops of hard brittle translucent resin. When chewed, the resin softens and becomes a bright white and opaque gum. The flavor is bitter at first, but after chewing releases a refreshing, slightly piney or cedar flavor.
The word mastic derives from the Greek verb μαστιχειν "to gnash the teeth", which is the source of the English word masticate.[1] The word mastic is a synonym for gumin many languages. ... Mastic contains antioxidants, and also has antibacterial and antifungal properties.[3]"

"Anti-inflammatory activity of Chios mastic gum is associated with inhibition of TNF-alpha induced oxidative stress" in Nutritional Journal (2012)
"Clinical studies have emphasized anti-inflammatory activity of Chios mastic gum [5,6]. This biological activity can be attributed to a variety of compounds. It contains triterpenes of the oleanane, euphane and lupine type [7,8]; alpha-tocopherol and polyphenols; the latter have been associated with a hypotensive effect of mastic [9]. Chios mastic possesses anti-bacterial activity [10,11], for which verbenone, alpha-terpineol, and linalool seem to be responsible.

Chios mastic gum has been extensively used for centuries in Mediterranean and Middle Eastern countries, both as a nutritional supplement and herbal remedy. Medical trials show that gum mastic may have cytoprotective or anti-acid effects on the gastrointestinal system [4] . Recent studies seem to suggest that gum mastic may exhibit antibacterial properties [39] and inhibit the proliferation of androgen-dependent prostate cancer [40]. This work makes an important addition to this list demonstrating potential role of antioxidant properties in the anti-inflammatory activity of the Chios mastic gum based on inhibition of PKC-dependent [Protein kinase C] NADPH [nicotinamide adenine dinucleotide phosphate-oxidase] oxidases."

"Pistacia lentiscus Resin Regulates Intestinal Damage and Inflammation in Trinitrobenzene Sulfonic Acid–Induced Colitis" in Journal of Medicinal Foods (2011)
"Mastic (Pistacia lentiscus) of the Anacardiaceae family has exhibited anti-inflammatory and antioxidant properties in patients with Crohn's disease. ... Histological amelioration of colitis (P≤.001) and significant differences in colonic indices occurred after 3 days of treatment. Daily administration of 100 mg of P. lentiscus powder/kg of body weight decreased all inflammatory cytokines (P≤.05), whereas 50 mg of P. lentiscus powder/kg of body weight and cortisone treatment reduced only ICAM-1 (P≤.05 and P≤.01, respectively). Malonaldehyde was significantly suppressed in all treated groups (P≤.01). IL-10 remained unchanged. Cytokines and malonaldehyde remained unaltered after 6 days of treatment. Thus P. lentiscus powder could possibly have a therapeutic role in Crohn's disease, regulating oxidant/antioxidant balance and modulating inflammation."

"Mastic gum has bactericidal activity on H. pylori in vivo."

"The results suggest that mastic significantly decreased the activity index and the plasma levels of IL-6 and CRP in patients with mildly to moderately active CD."

Does vitamin E supplementation improve Crohn's symptoms?

Vitamin E from Wikipedia

Vitamin E from CyberLipid Center
"The term "vitamin E" should be used for all tocopherol, tocotrienol and tocomonoenol derivatives exhibiting the biological activity of d-a-tocopherol. The term "tocopherol" should be used for all methyl tocols. Since tocotrienols have some vitamin E activity, "tocopherol" is not synonymous with "vitamin E"."

"Advanced Plan: Supplements" from Mercola.com
"Keep in mind that your body can easily distinguish between natural and synthetic vitamins, and natural vitamin E is between two and three times as bioactive as the same amount of synthetic vitamin E. Natural vitamin E is always listed as the "d-" form (d-alpha-tocopherol, d-beta-tocopherol, etc.). Synthetic vitamin E is listed as " dl-" forms.

But your optimal source for vitamin E is from your food. A 2002 study suggested that if you consume plenty of vegetables (about one pound of vegetables for every 50 pounds of body weight), the antioxidants in the vegetables may provide as much, or more, protection as vitamin E supplements."

"Adequacy of Nutritional Intake in a Canadian Population of Patients with Crohn’s Disease" in Journal of the American Dietetic Association (2007)
"Micronutrient intakes were suboptimal most notably for folate, vitamins C, E, and calcium. ...  In conclusion, in this population sample, a large number of ambulatory patients with Crohn’s disease have suboptimal dietary patterns despite a normal BMI and inactive disease. Dietary counseling and supplementation may be warranted in this patient population."

"Food intake in patients with Inflammatory Bowel Disease" in ABCD Arq Bras Cir Dig (2011) [full article]
"There was deficiency in food intake in both CD and UC in active and in remission. These deficiencies
are mainly related to the intake of macronutrients, energy and fiber and micronutrients, including ... tocopherol...."

"A Novel Water-Soluble Vitamin E Derivative Protects Against Experimental Colitis in Rats" in
Antioxidants & Redox Signaling (2008)
"This study was designed to investigate the effects of water-soluble vitamin E derivative, 2-(α-d-glucopyranosyl) methyl-2,5,7,8-tetramethylchroman-6-ol (TMG), on experimental colitis in rats. ... These results suggest that TMG is effective for the treatment of colitis in rats induced by TNBS [trinitrobenzene sulfonic acid]."
