Mastic (Pistacia lentiscus): Effects on Prostate Health and Urinary Benefits

Abstract

Mastic (Pistacia lentiscus), a resin obtained from the mastic tree native to the Mediterranean region, has been used for centuries in traditional medicine. Modern scientific inquiry has begun to explore its pharmacological activities, including antimicrobial, antioxidant, anti-inflammatory, and anti-cancer effects. This article provides an in-depth scholarly analysis of the known data regarding mastic’s potential benefits for prostate health, its ingestion methods, its effects on urinary function, and its broader implications for men’s health. We aim to bridge traditional use with emerging evidence in urological and prostate research.

1. Introduction to Mastic

Mastic is a natural resin derived from the bark of Pistacia lentiscus var. chia, primarily grown on the Greek island of Chios. Often called “tears of Chios,” mastic resin has been traditionally used in Mediterranean medicine for gastrointestinal health, oral hygiene, and wound healing. Recent research has shifted attention to its systemic effects, including possible implications for prostate and urinary health.

2. Chemical Composition

Mastic is composed of a complex mixture of bioactive compounds, including:

  • Monoterpenes: α-pinene, β-myrcene, limonene
  • Triterpenic acids: masticadienonic and isomasticadienonic acids
  • Polyphenols and flavonoids: Known for their antioxidant and anti-inflammatory effects

These compounds are thought to contribute to mastic’s observed therapeutic properties in a wide range of biological systems.

3. Effects of Mastic on Prostate Health

3.1 Anti-Inflammatory Activity

Chronic inflammation is a known contributor to benign prostatic hyperplasia (BPH) and possibly prostate cancer. Mastic exhibits strong anti-inflammatory effects, largely through inhibition of cyclooxygenase-2 (COX-2) and nitric oxide synthesis, both of which are elevated in inflammatory prostate conditions.

  • Relevant study: In vitro studies have shown that mastic oil inhibits pro-inflammatory cytokines such as IL-6 and TNF-α, which are overexpressed in inflamed prostate tissue.

3.2 Antioxidant Mechanisms

Oxidative stress has been implicated in the pathogenesis of both BPH and prostate cancer. Mastic’s polyphenolic contentcontributes to scavenging free radicals and reducing lipid peroxidation in prostate tissue.

  • Mechanism: Mastic increases levels of superoxide dismutase (SOD) and glutathione (GSH), two key antioxidant enzymes in the prostate.

3.3 Antiproliferative and Anti-Cancer Potential

Emerging data suggests that mastic extracts may have cytotoxic effects on prostate cancer cell lines, potentially through the downregulation of androgen receptors and induction of apoptosis.

  • Study highlight: A 2022 Journal of Ethnopharmacology study showed mastic resin extract inhibited the proliferation of LNCaP prostate cancer cells in vitro, with dose-dependent cytotoxicity.

4. Mastic and Urinary Health

Mastic’s anti-inflammatory and antimicrobial properties may also extend to the urinary tract:

  • Relief of Lower Urinary Tract Symptoms (LUTS): Reduction in prostate inflammation indirectly improves urinary flow, reduces urgency, and decreases nocturia.
  • Antimicrobial effects: Active against E. coli, Enterococcus faecalis, and Klebsiella pneumoniae—common culprits in urinary tract infections (UTIs).
  • Bladder Protection: Animal studies have suggested that mastic oil may exert a protective effect on bladder epithelium under inflammatory conditions.

5. Ingestion Methods

5.1 Traditional Use

  • Chewing gum form: Mastic is chewed directly to release essential oils. Though absorption through oral mucosa is minimal, this form is useful for gastrointestinal benefits and general detoxification.

5.2 Capsules and Resin Extracts

  • Standardized supplements: Capsules containing 350–1000 mg mastic extract per dose are commercially available and are the preferred method for systemic benefits.
  • Oil-infused products: Often combined with olive oil or other carriers to improve bioavailability.

Dosage:

  • For general health: 350–500 mg/day
  • For therapeutic purposes (e.g., BPH, prostate inflammation): 1000–1500 mg/day, divided into two or three doses

Note: Mastic is generally well tolerated, but high doses may cause mild gastrointestinal upset in sensitive individuals.

6. Safety, Interactions, and Contraindications

  • Safety profile: Considered safe by the European Medicines Agency (EMA) when used in recommended doses.
  • Drug interactions: No significant interactions documented, but caution is advised with immunosuppressants or NSAIDs due to overlapping anti-inflammatory effects.
  • Contraindications: Allergy to tree resins or members of the Anacardiaceae family.

7. Conclusion

Mastic (Pistacia lentiscus) presents promising therapeutic potential for enhancing prostate health, alleviating urinary symptoms, and possibly offering protective effects against prostate malignancies. While more clinical trials are needed, existing in vitro and animal data support its role as a complementary nutraceutical in men’s health strategies. Its ease of ingestion, excellent safety profile, and long history of traditional use further enhance its candidacy for integration into prostate health protocols.
