7 Amazing Healing Powers of Aloe Vera
1. Skin Aging Aloe is an established topical remedy for skin. But a 2009 study found that taking aloe orally reduces facial wrinkles. In the study, 30 healthy women aged 45 or older received aloe vera gel as a supplement. One group took a low dose (1,200 mg/day) and the second group took a high-dose (3,600 mg/day). The researchers measured signs of skin aging at the beginning and end of the study. After just 90 days, the researchers found that facial wrinkles improved significantly in both groups. However, in the lower-dose group, facial elasticity also improved. How does it work? The researchers found that aloe increased collagen production, resulting in improved skin structure and fewer wrinkles. They also found that aloe decreased gene activity that causes collagen damage. 2. Psoriasis Swedish researchers found that a cream containing aloe vera is effective in treating psoriasis. They conducted a double-blind, placebo-controlled study of 60 patients with psoriasis. Patients were given either an aloe vera extract (0.5%) cream or a placebo cream to apply three times a day for five consecutive days per week. The study lasted 16 weeks, with only four weeks of active treatment and 12 months of follow-up. By the end of the study, the aloe vera cream cured 25 of 30 psoriasis patients, or 83.3%. Only 2 of 30 patients in the placebo group were cured (6.6%). 3. Cancer Consistent with its other skin benefits, aloe vera may also prevent and treat skin cancer. A study from the University of Belgrade School of Medicine found that aloe vera and its constituents inhibit skin cell proliferation associated with skin cancer. The researchers irradiated human skin cells to simulate sun damage and trigger the process of proliferation that leads to skin tumors. They found that treating cells with aloe-emodin, a constituent of aloe, significantly inhibited proliferation. This confirmed aloe's benefit in halting tumor progression following sun exposure. But its cancer effects aren't limited to skin. Studies also show that aloe vera may help prevent cervical cancer. A study published in the Asian Pacific Journal of Cancer Prevention found that a cream containing aloe vera, curcumin, reetha, and amla (brand name “Basant”) is an effective and safe therapy for the clearance of cervical human papillomavirus (HPV) infection. Researchers studied a group of women with HPV that had not yet progressed to high-grade cervical neoplasias (i.e., cervical pre-cancer). Of the women who used the Basant vaginal cream for 30 consecutive days, 87.7% cleared the HPV infection compared to 73.3% of the placebo group.
