Medicinal Facts

Acmella oleracea, commonly known as Paracress, is renowned for its bioactive compound spilanthol, an alkylamide with significant anesthetic and anti-inflammatory properties. This plant sits at the intersection of traditional Amazonian medicine, where it is used for toothaches and oral health, and modern pharmacological research exploring its potential in pain management and anti-inflammatory applications. Its unique mechanism of action involves modulation of TRPV1 receptors, which are crucial in pain and inflammation pathways. The plant's traditional uses are supported by emerging evidence on its efficacy in modulating inflammatory cytokines and providing localized analgesia.

What it helps with

Pain relief & anesthesia

Spilanthol, the primary active compound, acts on TRPV1 receptors, which are involved in the sensation of pain and heat. By modulating these receptors, spilanthol provides a numbing effect, traditionally used for toothaches and oral discomfort. Animal studies support its efficacy, showing reduced pain perception and inflammation.

Inflammatory conditions

Spilanthol inhibits the release of pro-inflammatory cytokines such as TNF-alpha and IL-1beta, which are pivotal in the inflammatory response. This action is mediated through the modulation of NF-kB signaling pathways. Preclinical studies demonstrate its potential in reducing inflammation, although human trials are limited.

Oral health

Traditionally used for its antimicrobial properties, spilanthol exhibits activity against oral pathogens by disrupting bacterial cell membranes. This contributes to its role in managing oral infections and maintaining oral hygiene. Evidence is primarily anecdotal and from traditional use, with limited clinical validation.

Immune modulation

Spilanthol may enhance immune function by modulating macrophage activity and cytokine production, potentially through pathways involving NF-kB and MAPK. This immunomodulatory effect is supported by in vitro studies, suggesting a role in bolstering immune defenses.

Skin health & wound healing

The anti-inflammatory and antimicrobial properties of spilanthol support its use in topical applications for skin conditions. It promotes wound healing by reducing local inflammation and preventing infection, with evidence from traditional use and preliminary in vitro studies.

Rheumatic pain

Spilanthol's modulation of TRPV1 and its anti-inflammatory effects suggest potential benefits for rheumatic conditions. It may reduce joint pain and inflammation, as supported by animal models, although human evidence is sparse.

Nervous system support

Beyond pain relief, spilanthol's action on TRPV1 receptors may offer neuroprotective benefits by modulating neuroinflammation. This is a speculative area of research, with potential implications for conditions like neuropathic pain.

Key active compounds

Spilanthol

An alkylamide responsible for the plant's anesthetic and anti-inflammatory properties. It modulates TRPV1 receptors and inhibits pro-inflammatory cytokines, but has limited bioavailability, which affects its systemic use.

Flavonoids

These compounds contribute to the plant's antioxidant profile, scavenging free radicals and supporting spilanthol's anti-inflammatory effects. They may also enhance the bioactive potential of spilanthol through synergistic interactions.

Polysaccharides

These components may support immune modulation by enhancing macrophage activity and cytokine production, although their specific mechanisms in Acmella oleracea are less well-characterized.

Essential oils

Comprising various terpenes, these oils contribute to the antimicrobial and aromatic properties of the plant, potentially enhancing the penetration and efficacy of spilanthol in topical applications.

Alkamides

Beyond spilanthol, other alkamides in the plant may contribute to its overall pharmacological profile, particularly in modulating inflammation and pain pathways.

Tannins

These polyphenolic compounds have astringent properties that may support the plant's traditional use in oral health by tightening tissues and reducing inflammation.

What the research says

Research on Acmella oleracea focuses on its pain-relieving and anti-inflammatory properties, primarily attributed to spilanthol. Animal studies highlight its efficacy in reducing pain perception and inflammation through TRPV1 modulation and cytokine inhibition. Human data are limited, but traditional use supports its application in oral health and localized pain relief. The main limitation is spilanthol's poor bioavailability, which restricts systemic effects. Formulation strategies, such as encapsulation or combination with other bioenhancers, are under investigation to improve its pharmacokinetic profile and broaden its therapeutic potential.

Typical dosage

For tea or infusion, use 1-2 teaspoons of dried leaves or flowers per cup of boiling water, steep for 10 minutes, and consume up to three times daily. For tinctures, take 10-20 drops in water or juice up to three times daily. Topical applications should be used as directed, typically applied to the affected area 2-3 times daily. Capsules and extracts should be used according to the manufacturer's instructions, typically not exceeding 500 mg per day.

About Paracress

Acmella oleracea, commonly known as Paracress, is a flowering herbaceous plant belonging to the Asteraceae family. Native to the tropics of Brazil and Peru, it is widely recognized for its unique numbing effect, which has earned it the nickname 'toothache plant'. The plant's active compound, spilanthol, is responsible for its analgesic properties, making it a popular traditional remedy for toothaches and oral discomfort. In addition to its pain-relieving capabilities, Acmella oleracea is traditionally used to support immune function and aid digestion. The plant's leaves and flowers are often used in teas and tinctures, while its extracts are incorporated into topical applications for skin care. Modern research suggests that spilanthol may possess anti-inflammatory and immune-boosting properties, although comprehensive clinical studies are limited.

Traditional Use

Acmella oleracea has a rich history of traditional use in various cultures, particularly in South America and Africa. Indigenous tribes have utilized the plant for centuries, primarily for its analgesic properties in treating toothaches and other pains. Its first documented medicinal use dates back to the 16th century when it was noted for its numbing effects. In traditional medicine systems, such as Ayurveda, it has been recognized for its ability to support digestive health and reduce inflammation. Over time, its applications have expanded, and it is now gaining attention in modern herbalism and natural health practices.

Preparations & Dosage

Preparations

Tea / Infusion: Boil water and pour over 1-2 teaspoons of dried Acmella oleracea leaves or flowers. Steep for 10 minutes, strain, and drink. Optionally, add honey or lemon for flavor.
Tincture: Use a dropper to add 10-20 drops of Acmella oleracea tincture to a glass of water or juice. Stir well and consume up to three times daily.
Topical application: Apply a small amount of Acmella oleracea extract or cream to the affected area. Gently massage until absorbed. Use 2-3 times daily.

Interactions & Warnings

Acmella oleracea may interact with sedative medications, potentially enhancing their effects. It should be used cautiously with other herbs or supplements that have sedative properties, such as valerian or kava. Individuals taking blood thinners or with bleeding disorders should consult a healthcare provider before use, as the plant may have mild blood-thinning effects. High doses may cause oral irritation or numbness.

Use with caution

Acmella oleracea should be used with caution by individuals with allergies to plants in the Asteraceae family. Pregnant or breastfeeding women should consult a healthcare provider before use. Excessive consumption may lead to numbness or irritation in the mouth.
