Research on Aloe Vera

Information below has been taken from this page: https://www.mskcc.org/cancer-care/integrative-medicine/herbs/aloe-vera

  • Aloe demonstrated antioxidant and anti-inflammatory properties, in vitro (9).
  • In clinical studies, an aloe cream was reported to be superior to silver sulfadiazine creams for the treatment of second-degree burns (21);
  • An aloe vaginal cream was found equally effective as an estrogen cream against vaginal atrophy in menopausal women (48);
  • An aloe gel was shown effective in skin graft donor-site healing (38);
  • An aloe ointment improved symptoms of acute radiation proctitis in patients receiving radiotherapy (39);
  • An aloe cream improved postoperative pain and discomfort, and promoted healing following pilonidal sinus excision (45)
  • A mouthwash containing aloe was shown to reduce plaque, gingivitis and S. mutans in the oral cavity in children, with the effects being comparable to chlorhexidine (46).
  • Systematic reviews indicate aloe’s effectiveness against oral lichen planus, while not causing any adverse effects compared to corticosteroids (37) and for reducing pain/burning sensation and affecting clinical improvement in patients with oral submucous fibrosis (41).
  • Aloe gel complex was shown to affect reductions in body weight and insulin resistance in obese individuals with pre-diabetes or early untreated diabetes mellitus (29); to prevent pressure ulcers in hospitalized orthopedic patients at risk of developing such ulcers (42); to prevent traumatic oral ulceration in patients with fixed orthodontic appliances (47); and to accelerate split-thickness skin graft donor-site healing (43).
  • Data also suggest that constituents of aloe, such as acemannan, aloeride, and di(2-ethylhexyl) phthalate (DEHP) have immunomodulating and anticancer effects (5) (7) (8) (34) (35).
  • Emodin from aloe inhibited cell proliferation and induced apoptosis in human liver cancer cell lines through p53- and p21-dependent pathways (4); along with enhancing the effects of radiation treatment (30).
  • Concurrent administration of aloe with chemotherapy may prevent oral mucositis in patients receiving chemotherapy (23); and benefit those with metastatic cancers (20)
  • Findings of topical use of aloe products to alleviate radiation-induced skin damage are inconsistent (1) (2) (3) (32) (36) (44) (49)
  • Emodin was also shown to inhibit cell proliferation and induce apoptosis in human liver cancer cell lines through p53- and p21-dependent pathways (4)
  • Acemannan, a carbohydrate fraction derived from Aloe vera leaf, was found to stimulate cytokine production in mouse macrophage cell line (5). It also exhibited immunomodulating activity by inducing maturation of dendritic cells (6)
  • Aloeride, a polysaccharide obtained from aloe vera juice, was reported to be a potent immunostimulator that acts by enhancing NF-kappa B activities (7)
  • In addition, di(2-ethylhexyl)phthalate (DEHP), isolated from Aloe vera, inhibited leukemic cells, in vitro (8).
