Tourism Innovation
In Karangrejek, Wonosari, researchers and community members are exploring how chemical science can transform Jamu into compelling tourism experiences 1 .
The Science Behind Jamu: Bioactive Compounds and Health Benefits
At its core, Jamu's efficacy lies in the complex phytochemical composition of its botanical ingredients containing a sophisticated pharmacy of bioactive molecules with demonstrated therapeutic properties 7 .
Turmeric (Kunyit)
Rich in curcuminoids with anti-inflammatory and antioxidant properties
Ginger (Jahe)
Contains gingerols with anti-nausea and digestive benefits
Aromatic Ginger (Kencur)
Essential oils with analgesic and anti-inflammatory effects
Temulawak
Xanthorrhizol provides hepatoprotective properties
| Jamu Ingredient | Primary Bioactive Compounds | Demonstrated Health Benefits |
|---|---|---|
| Turmeric (Kunyit) | Curcumin, Demethoxycurcumin | Anti-inflammatory, Antioxidant, Antimicrobial |
| Ginger (Jahe) | Gingerol, Shogaol, Zingerone | Anti-nausea, Anti-inflammatory, Digestive aid |
| Aromatic Ginger (Kencur) | Ethyl-p-methoxycinnamate, Ethyl cinnamate | Analgesic, Anti-inflammatory, Respiratory health |
| Temulawak | Xanthorrhizol, Curcuminoids | Liver protection, Digestive stimulant, Anti-inflammatory |
| Sappan Wood (Secang) | Brazilin, Caesalpin | Antioxidant, Antimicrobial, Anti-inflammatory |
Multi-Target Mechanisms
These compounds typically function through multi-target mechanisms, interacting with various biological pathways simultaneously—a characteristic that distinguishes traditional herbal medicine from single-compound pharmaceuticals 2 .
