Extracts or essential oils of basil, which provide concentrated amounts of plant compounds, are typically tested instead of whole leaves ( 8).

Today, scientists study potential medicinal benefits of basil. Health Benefitsīasil is not only a popular folk remedy for ailments like nausea and bug bites but also widely utilized in traditional Chinese medicine, Ayurvedic medicine and other holistic medicine systems ( 4, 6, 7). Basil also supplies plant compounds, which contribute aroma, flavor and health benefits. Summaryīecause basil is generally used in small quantities, the only substantial nutrient it provides is vitamin K. That’s why oils derived from basil and other plants are called essential oils ( 4). In addition, these compounds give basil its “essence” - or distinct aroma and flavor. Therefore, neither is a significant source of most nutrients - except vitamin K.īasil also supplies beneficial plant compounds that have antioxidant, anti-inflammatory and other health properties ( 4, 5). Though dried basil is more concentrated in nutrients, you use less in recipes compared to fresh. The main type of basil for supplements and herbal tea is holy basil, which is a related but different species. Sweet basil is most widely used for cooking, but many other varieties - with slightly different flavor profiles - are available.

It is added to some Thai dishes because of its distinct flavor ( 1). The basil commonly used in supplements and herbal tea is holy basil - sometimes called tulsi - which is the O. Works well in salads or tossed with tomatoes and olive oil.

Lettuce basil: Features large, wrinkled, soft leaves with a licorice-like flavor.

Commonly served with legumes or spicy, stir-fried vegetables.

Thai basil: Has an anise-licorice flavor and is commonly used in Thai and Southeast Asian dishes.

Forms a compact bush with small leaves and grows well in a pot.

Bush or Greek basil: Has a strong aroma but mild flavor, so it can be substituted for sweet basil.

Sweet basil: The most widely grown, popular basil, renowned for its use in Italian dishes.

In principle, this effect can be used to increase the herb stability, but the light exposure is still too strong for appropriate sales quality.įuture trials will have to check whether shorter application times at the end of the cultivation period increase the stability by lowering weight on the plant head without weakening overall height and fresh mass of plants.The scientific name of the basil commonly purchased for cooking is Ocimum basilicum (abbreviated O. The results confirm the results of the preliminary climate chambers experiments: even under varying daylight conditions, light stimuli lead to significantly shorter basil plants with thinner stems and less fresh mass. Parameters during the tests were height, width, stem length, and stem width as well as the width of the leaves. Natural sunlight was supplemented with HPS lamps.

In succession, the aim of the main study was to validate the preliminary results in practice and to investigate whether the outlined effects could lead to an increase in stability.Ī greenhouse trial was carried out at producer Gartenbau Schulz, Papenburg, Germany, exposing basil to 1,000 ♞ light stimuli by a white-blue LED during the entire cultivation period (every 10 min for 30 s from 6 am to 8 pm).

Those experiments provided evidence of reduced height and fresh mass of basil plants, as well as thinner stems and wider leaves. In this study, preliminary experiments were carried out in climate chambers regarding the effects of additional light intensities and qualities as well as sun fleck duration on young basil plants ( Ocimum basilicum L.). Due to a lack of light and a morphologically determined top heaviness, the cultivation of potted herbs leads to unstable plants in winter months.įormer studies suggest that plants become more compact with high intensity pulsed light exposure (>1,000 ♞).
