Almond oil [Oleum amygdalae] has long been used in complementary medicine circles for its numerous health benefits. Although no conclusive scientific data exists currently, almonds and almond oil have many properties including anti-inflammatory, immunity-boosting and anti-hepatotoxicity effects. Further, associations between almond oil and improved bowel transit have been made, which consequently reduces irritable bowel syndrome symptoms. Further, some studies show a reduced incidence of colonic cancer. Moreover, cardiovascular benefits have also been identified with almond oil elevating the levels of so-called 'good cholesterol', high-density lipoproteins (HDL), whilst it reduces low-density lipoproteins (LDL). Historically, almond oil had been used in Ancient Chinese, Ayurvedic and Greco-Persian schools of Medicine to treat dry skin conditions such as psoriasis and eczema. Further, it is through anecdotal evidence and clinical experiences that almond oil seemingly reduces hypertrophic scarring post-operatively, smoothes and rejuvenates skin. Almond oil has emollient and sclerosant properties and, therefore, has been used to improve complexion and skin tone. Further studies looking into the use of almond oil post-operatively for the reduction of scarring are suggested.

ABSTRACT: Hydroxypropylmethylcellulose based edible films with and without antioxidant additives were characterised as to their microstructure, water vapour and oxygen permeability, mechanical behaviour, optical properties and protective ability against lipid oxidation. The corresponding film-forming dispersions were also used to coat toasted almonds in order to test their effectiveness at protecting against rancidity development. The efficiency of three additives (ascorbic acid, citric acid or ginger essential oil) was tested and compared with antioxidant-free coatings. A cross-linking effect in the film matrices containing ascorbic or citric acid was detected through the analysis of the film microstructure, mechanical behaviour and barrier properties to oxygen and water vapour. These films were the most effective protectors against oxidation of almonds, due to both their antioxidant effect and the tighter structure which leads to lower oxygen permeability. In films with ginger oil, the hydrophobic effect markedly reduced water vapour permeability at low temperatures, but protection against lipid oxidation was less effective at long storage times.Journal of Food Engineering 06/2011; 104(4):649-656.

ABSTRACT: Objective: To evaluate the effectiveness of topical 0.03% tacrolimus dissolved in almond oil (AO) or linseed oil (LO) in treating experimentally induced keratoconjunctivitis sicca (KCS) in rabbits. Materials and methods: KCS was induced in 25 male New Zealand white rabbits with 1% atropine sulfate eye drops. The rabbits were divided into five groups: Group C (control), Group A (AO), Group L (LO), Group TA (tacrolimus in AO), and Group TL (tacrolimus in LO). The induction of KCS with atropine continued for 12 weeks, and the animals were evaluated weekly using the Schirmer’s Tear Test I (STT I), the Fluorescein Test (FT), and the Rose Bengal Test (RBT). Ocular cytology was evaluated monthly. The rabbits were euthanized at the end of the experiment for histopathological analysis. Results: A significant increase in STT I values after KCS induction was observed in all treatment groups, with group L presenting the greatest increase. There was a more rapid resolution of corneal ulcers observed in groups A and L as assessed by the FT, and the results of the RBT were similar in all groups. Groups TA and TL exhibited reduced edema and corneal and conjunctival degeneration in histopathological evaluations. There was a significant increase in the number of caliciform cells in all treatment groups, especially in groups TA and TL. Conclusions: The results demonstrate that not only tacrolimus, due to its immunosuppressive effects, but also the oily vehicles used for tacrolimus dilution, possibly due to their anti-inflammatory properties, helped to improve the symptoms of dry eye induced in rabbits. In the future, these results may be used to create new topical ophthalmic formulations for the treatment of KCS.
