Herbal antioxidant in clinical practice: a review

Area of Science:

• Biochemistry and Molecular Biology
• Nutritional Science
• Herbal Medicine

Background:

• Free radicals cause oxidative stress, damaging vital cellular components like DNA, lipids, and proteins.
• The body employs natural defenses including enzymes and endogenous antioxidants (e.g., glutathione).
• Exogenous antioxidants, such as vitamins A, C, E, and carotenoids, are crucial for mitigating radical damage.

Purpose of the Study:

• To discuss the role of antioxidants in combating free-radical damage.
• To explore well-known and lesser-known herbs that can optimize antioxidant status.
• To highlight the preventive health benefits associated with enhanced antioxidant levels.

Main Methods:

• Literature review and discussion of scientific evidence.
• Analysis of antioxidant compounds and their mechanisms of action.
• Exploration of specific herbs with antioxidant properties.

Main Results:

• Free radicals are implicated in the damage of numerous biochemical components.
• A variety of natural and nutrient-based antioxidants exist, each with specific cellular targets.
• Certain herbs may contribute significantly to the body's overall antioxidant defense system.

Conclusions:

• Optimizing antioxidant status through diet and herbal supplements may offer preventive health benefits.
• Understanding the specialized functions of antioxidants, like carotenoids in the macula, is essential.
• Further research into the efficacy of various herbs for antioxidant support is warranted.
