A reader last time wanted your advice about treating this nasty skin condition. Again, many of you have come to her aid. One reader says it’s vital to feed the immune system with a daily regimen that includes 500 IU of oil-based natural vitamin E, 1000 mg vitamin C (ideally calcium ascorbate) and 1000 mg evening primrose oil. It’s important to buy quality supplies. Whenever her mother buys lower-grade brands, her psoriasis returns. It’s also important to avoid pesticides, solvents and other poisons. Hemp oil is another suggestion. Its blend of omega-3, -6 and -9, and GLAs can have a potent effect. If omega-3 can help, the best way of taking it is as shark liver oil. Try aloe vera as a drink, suggests one reader, or Mercy Cream, says another. Then there’s a range of products called M-Folia, which contains an extract of Mahonia aquifolium.
