one case series were eligible for review ; also , scar assessment scales and pain severity scales were highly heterogeneous .
Conclusions : The studies differed regarding the delivery of dry needling or local acupuncture for scar treatment . Differences included treatment frequency , duration , number of treatments , selection of needle insertion sites , number of needles used , angle of needle placement , and use of manual needling manipulation .
Aromatherapy during nitrous oxide / oxygen inhalation ( paired t-test , P < 0.001 ). There was no significant difference in the increase rate of gag reflex values between the positive control and aromatherapy interventions , but it was significantly lower after the placebo intervention ( repeated measures analysis of variance , P = 0.003 ; post-hoc test , P = 0.83 and P = 0.02 ).
Conclusion : Aromatherapy with peppermint essential oil has the potential for reducing gag reflex during dental procedures .
Decreases in pain severity and intensity were significantly greater in all three intervention groups than in the control group .
Conclusions : Inhalation of lavender oil and its major volatile components effectively reduced the quality , severity , and intensity of postherpetic pain , suggesting that lavender oil , linalool , and linalyl acetate may each be an effective intervention for reducing pain in patients with postherpetic neuralgia .

Background : Sensitive gag reflexes prevent dental patients from receiving appropriate treatment . Aromatherapy helps patients relax during dental procedures . However , the effect of aromatherapy on the gag reflex caused by the stimulation of the oral cavity is unknown . This study aimed to evaluate whether aromatherapy reduces gag reflexes during oral stimulation .
Methods : In this randomized , placebocontrolled , single-blind , crossover study , the gag reflexes of 24 healthy individuals ( 12 females and 12 males ; mean age : 34.3 ± 9.5 years ) were quantified . A standard saliva ejector was slowly guided down the participant ’ s throat to determine the maximum tolerance of the gag reflex , and the insertion distance was measured to quantify the gag reflex . All individuals participated in an aromatherapy session with peppermint essential oil and a placebo session with distilled water . The gag reflex was quantified before ( baseline ) and after each session . Another measurement was performed using nitrous oxide / oxygen inhalation as a positive control .
Results : Gag reflex values significantly increased after aromatherapy with both peppermint essential oil and placebo compared to baseline values ( paired t-test , P < 0.001 and P = 0.014 , respectively ). The gag reflex value also increased significantly

Background : Postherpetic neuralgia ( PHN ) causes severe pain which can lead to decreased quality-of-life . This study aimed to evaluate the effects of inhalation of lavender ( Lavandula angustifolia ) oil and its major components ( linalool and linalyl acetate ) on the pain in patients with PHN .
Methods : This study was performed at an outpatient clinic . Sixty-four patients with postherpetic neuralgia were randomly allocated to a control group ( almond oil ) or one of three experimental groups ( lavender oil , linalool , or linalyl acetate diluted in almond oil at concentration of 1 % v / v ), and the participants inhaled the aroma by natural breathing . Quality , severity , and intensity of pain were measured before and after the intervention .
Results : Six patients discontinued the intervention for personal reasons ; hence , data from 58 patients were analyzed ( control group , n = 14 ; 1 % lavender oil group , n = 15 ; 1 % linalool , n = 15 ; 1 % linalyl acetate , n = 14 ). Reduction in sensory pain was greater in the 1 % lavender oil group , 1 % linalool group , and 1 % linalyl acetate group than in the control group ( all P < 0.001 ). Reduction in affective pain was greater in the 1 % lavender group ( P < 0.001 ) and the 1 % linalool group ( P = 0.007 ) than in the control group .

Variation of the essential oil components of Citrus aurantium leaves upon using different distillation techniques and evaluation of their antioxidant , antidiabetic , and neuroprotective effect against Alzheimer ’ s disease .

Citrus fruit essential oil is considered one of the widely studied essential oils while its leaves attract less attention although being rich in nearly the same composition as the peel and flowers . The leaves of bitter orange or sour orange ( Citrus aurantium L .) were extracted using three different techniques namely ; hydrodistillation ( HD ), steam distillation ( SD ), and microwave-assisted distillation ( MV ) to compare their chemical composition . The three essential oil samples were analyzed through GC / FID and GC / MS analyses . The samples were tested in vitro using different antioxidant techniques ( DPPH , ABTS , CUPRAC , FRAP , PBD , and MCA ), neuroprotective enzyme inhibitory activities ( acetylcholine and butyl choline enzymes ), and antidiabetic activities ( α-amylase and α-glucosidase ). The results showed that thirty-five volatile ingredients were detected and quantified . Monoterpenes represented the most abundant class in the three essential oils followed by sesquiterpenes . C . aurantium essential oil carried potential antioxidant activity where SD exhibited the highest antioxidant activity , with values arranged in the following order : FRAP ( 200.43 mg TE / g ), CUPRAC ( 138.69 mg TE / g ), ABTS ( 129.49 mg TE / g ), and DPPH ( 51.67 mg TE / g ). SD essential oil also presented the most potent α-amylase
