Recommended Dosage and Use:

  • Oral Ingestion:
    • Extract: For standardized extracts (based on triterpene content like asiaticoside, asiatic acid, etc.), a daily dose of 60mg to 120mg is often recommended. Some sources suggest 60mg taken 2-3 times a day.
    • Dried Leaf: Taking 600mg of dried leaf three times a day, or drinking it as a tea (600mg steeped in 150ml of water) three times a day, has been suggested.
    • Liquid Extract/Tincture: Depending on the product, 1/2 to 1 teaspoon (3-5ml) of liquid extract or 2 to 4 teaspoons (10-20ml) of tincture daily may be recommended.
  • Topical Application (Skin): Applying a cream containing 1% Centella asiatica extract daily is generally suggested. For cosmetics, it is important to follow the product's specific instructions.

Disclaimer: The dosages above are for general reference only. The appropriate dose can vary depending on an individual's health condition, age, and purpose of use. Always consult a healthcare professional, especially when using it for therapeutic purposes.

Potential Side Effects:

  • Oral Ingestion: Generally well-tolerated, but some sensitive individuals may experience gastrointestinal upset (nausea, stomach pain), headache, dizziness, or drowsiness. Drowsiness may occur at high doses.
  • Topical Application: Skin irritation, allergic contact dermatitis, itching, and a burning sensation are rarely reported. A patch test is recommended before use.
  • Potential Liver Toxicity: Although very rare, cases of liver damage (jaundice, hepatitis) have been reported following ingestion. Caution is needed, especially with long-term or high-dose use. Individuals with pre-existing liver disease should avoid it.

Precautions and Contraindications:

  • Pregnancy and Breastfeeding: Oral ingestion during pregnancy should be avoided as its safety has not been established. While topical application is considered relatively safe, consultation with a professional is necessary. There is insufficient safety information for use during breastfeeding, so it is best to avoid it.
  • Liver Disease Patients: Due to the risk of liver toxicity, individuals with liver disease should avoid using Centella asiatica.
  • Before and After Surgery: Centella asiatica may slow blood clotting. It is necessary to consult with your surgeon before any procedure.
  • Allergies: Individuals with an allergy to Centella asiatica or other plants in the Apiaceae family (like parsley, carrots, celery) should avoid it.

Drug Interactions:

  • Sedatives/Hypnotics: As Centella asiatica may have a sedative effect, taking it with sedatives or sleeping pills can cause excessive drowsiness. Use with caution. (e.g., barbiturates, benzodiazepines).
  • Hepatotoxic Drugs: Combining it with drugs that can be harsh on the liver (e.g., high doses of acetaminophen, some antifungals, statins) may increase the risk of liver damage.
  • Anticoagulants/Antiplatelets: In theory, it may affect blood clotting. Consultation with a doctor is needed if taking anticoagulants (e.g., warfarin) or antiplatelets (e.g., aspirin).
  • Diabetes/Cholesterol Medications: Some research suggests it may affect blood sugar or cholesterol levels, so consultation with a doctor is necessary if you are taking related medications.

While Centella asiatica offers many benefits, safe use requires adhering to recommended dosages and considering your health status. If you are taking medication, have an underlying health condition, or are pregnant or breastfeeding, it is wise to consult a doctor or pharmacist before using any Centella asiatica product.

6.3. Coexisting with Nature: Sustainable Harvesting and Ethical Sourcing

As the popularity and demand for Centella asiatica grow, the importance of sustainably securing and ethically sourcing this valuable plant resource also increases. Indiscriminate harvesting can destroy ecosystems and threaten its natural habitats, while unethical labor practices can also be an issue.

Sustainable Harvesting:

  • Problems with Wildcrafting: Most Centella asiatica is harvested from the wild. Excessive and indiscriminate harvesting can lead to population decline, loss of genetic diversity, and habitat destruction.
  • Sustainable Methods: This involves regulating harvest volumes based on regeneration rates, selectively harvesting only necessary parts (like leaves and stems) instead of uprooting the entire plant, and timing the harvest to coincide with peak active ingredient levels while respecting the plant's life cycle.
  • Cultivation Technology: To reduce reliance on wild harvesting and ensure a stable supply, developing cultivation technology is crucial. Recently, there have been attempts to increase productivity and quality using smart farm technology. Eco-friendly extraction processes, such as ECO-PULSE™ Centella, are also being developed to reduce energy consumption and carbon emissions.

Ethical Sourcing:

  • Fair Prices and Labor Conditions: Harvesting is often done by women in underdeveloped regions. Paying them a fair price and providing a safe working environment is key to an ethical supply chain. International organizations like the UEBT (Union for Ethical BioTrade) promote projects that ensure fair wages and support community development.
  • Transparency and Traceability: It is important to ensure transparency throughout the supply chain and have a system to trace the origin of the raw materials. Some cosmetic brands use Centella asiatica from Madagascar with GACP (Good Agricultural and Collection Practices) certification and strive to build an ethical, traceable supply chain.
  • Biodiversity Conservation: Efforts to respect and conserve the biodiversity of the harvesting areas are necessary.

As consumers, we can participate in these efforts by choosing products that are sustainably and ethically sourced. Look for certifications like FairWild or UEBT, or refer to a company's sustainability reports. A responsible attitude from producers, companies, and consumers alike is necessary to enjoy the gift of Centella asiatica for a long time to come.
