Healing Properties

  • Antibiotic:
  • Antibacterial:
  • Brain Health: Powerful antioxidant.
  • Cognition: Improves learning and memory functions.[1]
  • Neuroprotective:[1] improving neuronal dysfunctions of the brain.
    • Defatted Walnut Meal Protein Hydrolysates (DWMPH): protects against neurotoxicity.
      • Alleviates oxidative stress
      • Reverses cholinergic dysfunction
      • Suppresses the release of pro-inflammatory cytokines (in the brain).

Disease / Symptom Treatment

  • Infections: Walnut oil can work synergistically with antibiotics to work against resistant Staphylococcus aureus (MRSA) strains in vitro.
  • Neurodegenerative Diseases:

    Abstract: In recent years, with an increase in the aging population, neurodegenerative diseases have attracted more and more attention. This study aimed to investigate the potential neuroprotective effect of defatted walnut meal protein hydrolysates (DWMPH) on neurotoxicity induced byD-galactose(D-gal) and aluminum chloride (AlCl3) in mice. The animal models were established by combining treatments withD-gal (200 mg/kg/day, subcutaneously) and AlCl3(100 mg/kg in drinking water)for 90 days. During the 90 days, 1 g/kg of DWMPH was administrated orally every day. The results indicated that DWMPH treatment alleviated oxidative stress, reversed cholinergic dysfunction,and suppressed the release of pro-inflammatory cytokines in the brains ofD-gal + AlCl3-treated mice,and thus improving the learning and memory functions of these mice, which was closely correlated with the strong antioxidant activity of DWMPH. This finding suggests that DWMPH might be a promising dietary supplement in improving neuronal dysfunctions of the brain.
