Perilla Aerial Part Extract
Also known as: Perilla, Shiso, Beefsteak plant, Japanese basil, Perilla frutescens
Overview
Perilla frutescens is an annual herb native to East Asia, particularly thriving in regions such as China, Korea, Japan, and the Himalayas. As a member of the Lamiaceae family, its aerial parts and seeds are prized for being rich in omega-3 fatty acids, flavonoids, vitamins, and minerals. Traditionally, Perilla has been incorporated into Traditional Chinese Medicine, valued for its diverse health benefits, particularly its anti-inflammatory, antioxidant, and anti-allergic properties. While promising effects have been observed in animal studies and cell cultures, clinical evidence in humans is still scarce, necessitating further research to thoroughly validate its efficacy and safety across different populations.
Benefits
Evidence suggests that *Perilla frutescens* may offer numerous health benefits, primarily its anti-allergic effects that could be particularly significant for young individuals suffering from allergic rhinoconjunctivitis. The herb exhibits anti-inflammatory and antioxidant actions, mainly evidenced by preclinical studies. It may also aid those with Mast Cell Activation Syndrome (MCAS) by helping reduce histamine levels and alleviate symptoms. Overall, individuals with allergic conditions are likely to benefit most from *Perilla*, although the current lack of extensive clinical trials limits the ability to quantify these benefits or thoroughly assess their clinical importance.
How it works
The bioactive compounds in *Perilla frutescens* are thought to operate through various mechanisms. They inhibit mediators of inflammation, thereby alleviating allergic reactions. Flavonoids like apigenin and luteolin assist in stabilizing mast cells by reducing histamine release. Additionally, the extracts modulate immune responses and may provide cardiovascular benefits, such as lipid-lowering effects and antioxidant activity. The use of advanced extraction methods, including compressed fluid techniques, enhances the bioactivity and absorption of these extracts.
Side effects
Generally, *Perilla frutescens* is considered safe for short-term consumption of up to 12 months. Some adverse reactions, such as allergic responses, may occur in over 5% of users. However, reports of rare serious side effects are limited, indicating a favorable safety profile. Limited data suggests potential drug interactions, thus it is prudent to use caution when combined with other medications. Users with allergies to *Perilla* or similar plants should refrain from its use. Moreover, those with MCAS or histamine intolerance should start with lower doses to monitor their reactions effectively.
Dosage
Currently, there are no established minimum effective doses for *Perilla frutescens*, and optimal dosages are not well-defined due to varying findings across studies. It is advisable to follow product labeling and consult healthcare professionals for personalized guidance. Although maximum safe doses are unspecified, *Perilla* extracts can be utilized safely for durations up to 12 months. For individuals with MCAS, it is recommended to consume the extract with meals or 30 minutes prior to eating to enhance symptom management. The seed extract is preferred over oil due to its stronger mast cell stabilizing effects, with effectiveness potentially increased by advanced extraction methods.
