Edibility / Culinary
- A popular spice and flavoring agent.
- With its strong sassafras odor and taste, used as an ingredient of root beers.
- Decoction or infusion of the bark used for loss of appetite, bloating, vomiting, flatulence, toothache, headaches, rheumatism, dysentery, to help expel flatus and to facilitate menses; colds, fevers, sinus infections and bronchitis.
- In Laguna, Philippines, decoction of leaves used for cough, nausea, vomiting, and hypertension. (7)
- In Agusan del Sur, used for abdominal discomfort and stomachaches. (8)
- Bark chewed for stomach troubles; also used in tuberculosis.
- According to Father Zlzina, the bark taken internally helps digestion; also for flatulence and as expectorant.
- Decoction of leaves also used for expelling gas.
- Used for diarrhea, menorrhagia, dysmenorrhea.
- Paste prepared from the bark is applied locally for neuralgic pains and severe headaches.
- Candida and other yeast infections.
- Used for treatment of scabies and lice.
- In Ayurveda, cinnamomum is used for diabetes, indigestion, and colds.
- Decoction: - One heaping teaspoon of powdered bark to a cup of boiling water; or, 0.5 to 1 g of bark to 7 oz of boiling water fir 5-10 minutes, then steep.
- Tincture: Moisten 200 parts of cinnamon bark evenly with ethanol and percolate to produce 1,000 parts of tincture. Use 3-4 cc three times daily.
• Cinnamomum mercadoi / Phytochemicals / Antimicrobial / Toxicity Testing: Phytochemical screening of crude methanol extract yielded saponins, condensed tannins, an unsaturated lactone ring and leucoanthocyanins. Mean lethal dose (LD50) of the extract in male mice is 5.2723 ± 0.2218 g/kg. (1)
• Analgesic: Study evaluated the analgesic activity of crude methanolic extract using the plantar test (Hargreaves method). Results showed strong protection (84%) against writhing at 500 mg/kg and 1000 mg/kg. The analgesic activity was comparable to aspirin. (1)
• Antimicrobial: In a study for antimicrobial activity, the crude extract showed moderate activity with against Staphylococcus aureus and strong antifungal activity against Microsporum canis. Cinnamic aldehyde was identified as the active fungitoxic constituent of cinnamon bark oil. (1)
• Antimicrobial / Bark Essential Oil: Essential oil of Cinnamomum mercadoi extracted by hydrodistillation was evaluated for antimicrobial activity. Results showed the Philippine cinnamon bark oil was highly effective against Staphylococcus aureus, Candida albicans and Fusarium moniliforme and moderately effective against E. coli. S. aureus from wound pathogens was highly susceptible while urine E. coli showed moderate susceptibility. (3)
• Fumigant / Oil: Study evaluated Cinnamomum mercadoi for potential fumigant activity against bean weevil, Callosobruchus chinensis. Extracts of C. mercadoi caused 57, 80, 90, 87, and 100% mortality of adult C. chinensis after 24 hours, when exposed to 10, 20, 30, 40, and 50 mg of extracted oil, respectively. (5)
• Antidiarrheal / Bark: Study evaluated the antidiarrheal activity of methanolic extracts of leaves and bark of Cinnamomum mercadoi using castor-oil induced diarrhea and gastrointestinal transit of charcoal meal in albino mice. In castor oil-induced diarrhea, the bark extract exhibited pronounced reduction of diarrheal feces by 78.1 % at oral dose 500 mg//kbw, comparable to standard drug loperamide (3mg.kg). The bark extract significantly reduced normal gastrointestinal transit. Leaf extract showed no activity. (6)
• Antimicrobial / Antioxidant / Leaf and Bark: Study evaluated leaf and bark methanolic extracts of C. mercadoi for antioxidant and antibacterial properties. The bark extract showed lower IC50 (12.7 ± 0.2 µg/mL) for DPPH radical scavenging activity than the leaf extract (91.7 ± 15.7 µg/mL). The bark extract also showed higher phenolic content (1331 mg GA/g) compared to the leaf extract (216 ±7 mg GA/g). The bark extract showed antibacterial activity against gram-positive bacterial (Bacillus subtilis and Staphylococcus aureus). (9)
• Secondary Metabolites / Cytotoxicity on Brine Shrimp Lethality / Leaves: Study of crude methanolic extract of leaves for secondary metabolites yielded flavonoids, tannins, terpenoids, and saponins. The extract showed cytotoxic effects against the nauplii with 73.3% mortality rate at 100 ppt (T1) and 50% mortality at 80 ppt (T2-LC50). (10)
• Antioxidant / Total Phenolics / Leaves: In a study of decoctions and ethanol leaf extracts of five Philippine medicinal plants for antioxidant potential, C. mercadoi EE yielded the highest total phenolics (570.58 mg GAE), which correlated well with its strong radical scavenging activity (91.97% at 500 ppm) against DPPH and high antioxidant capacities (149.91 AAE, 209.98 BHTE). Results suggest potential for use as natural antioxidant. (11)
