What are the morphological characteristics of this plant?
Arachis hypogaeal has a taproot system, pinnately compound leaves with four leaflets, and trifoliate flowers that produce fruit via geocarpy. The stems are typically herbaceous and can grow in an erect or trailing manner depending on the specific cultivar. Small yellow flowers emerge from the axils of the leaves before the plant undergoes a unique reproductive process. After pollination, the flower pedicel elongates and pushes the developing ovary into the soil to mature into a pod. These subterranean pods contain two to four seeds, which are commonly known as peanuts.
What is the geographical distribution of this plant?
This plant is native to the tropical and subtropical regions of South America, specifically concentrated in areas of Brazil, Argentina, Paraguay, and Bolivia. While its wild ancestors originated in these warm climates, cultivation has expanded globally to many other tropical regions. It is now widely grown in Africa, Asia, and parts of North America where the soil and temperature are suitable for peanut production. The distribution is heavily influenced by the requirement for warm growing seasons and well-drained sandy soils. Consequently, major commercial hubs are found in countries like China, India, and the United States.
How is this plant cultivated?
This plant, known commonly as the peanut, requires warm temperatures between 25 and 30 degrees Celsius and well-draining, sandy loam soil to thrive.
Farmers typically sow the seeds in the spring once the danger of frost has completely passed. Because the fruit develops underground, the soil must remain loose to allow the pegs to penetrate the earth easily. Regular irrigation is necessary during the flowering stage to ensure a successful crop yield.
Proper nitrogen fixation occurs through a symbiotic relationship with soil bacteria, which reduces the need for heavy chemical fertilizers.
What parts of this plant are used medicinally?
This plant Arachis hypogaea provides medicinal benefits through its leaves, roots, seeds, shells, and stems. The leaves and stems are often prepared as decoctions to help alleviate various inflammatory conditions or digestive issues. Extracts from the roots are sometimes utilized for their potential properties in treating specific ailments in traditional practices. The seeds serve as a concentrated source of nutrients and oils that support skin health and overall wellness. Additionally, the shells can be processed to aid in digestive regularity or used in topical applications.
According to a study published by "Physiology and molecular biology of plants : an international journal of functional plant biology", the provided text contains no information regarding the medicinal use of herb parts of the plant Arachis hypogaeas. The study focuses on the photosynthetic characteristics of twelve peanut genotypes under different irrigation treatments at 80 days after sowing. Data provided includes a cumulative evaporative demand of 412 mm and relative water content in leaves ranging from 93.5 % in T1 to 77.2 % in T3. Net photosynthetic rates were measured at 29.6 μmol m(-2) s(-1) in T2 and 24.3 μmol m(-2) s(-1) in T3. The de-epoxidation state was recorded at 38 % in T1 and T2 and increased to 47 % in T3.

What are the pharmacological activities of Arachis hypogaea?
This plant has demonstrated significant pharmacological activities including anti-inflammatory, antimicrobial, antioxidant, antitumor, and hepatoprotective properties. Its bioactive compounds work to neutralize free radicals, which provides a robust antioxidant effect for cellular protection. These chemical constituents also help reduce swelling and inhibit the growth of various harmful microbes. Furthermore, specific extracts from the plant have shown potential in suppressing tumor cell proliferation and protecting liver tissues from chemical damage. Such diverse biological actions make it a subject of interest for therapeutic research.
According to a study published by "Toxicology in vitro : an international journal published in association with BIBRA", Arachis hypogaeus contains the isoflavonoid Biochanin A. This substance has shown anti-inflammatary effects through comprehensive in vitro tests. Biochanin A demonstrated a high binding affinity for the G6PD receptor during molecular docking experiments. In A549 cells, it substantially decreased the expression of G6PD and other markers related to inflammation and metastasis. These findings suggest that Biochanin A has potential as a therapeutic agent in cancer treatment by targeting G6PD and related pathways.
The primary pharmacological activities of this plant are shown in the list below.
- anti-inflamatory
- antimicrobial

What medicinal compounds this plant contains?
This plant contains medicinal compounds such as resveratrol, ascorbic acid, peanut protein hydrolysates, and t-resveratrol, though it also produces the toxic aflatoxin B1. Resveratrol and its derivative t-resveratrol are known for their potent antioxidant and anti-inflammatory properties. The presence of ascorbic acid provides essential vitamin C to support immune function and skin health. Additionally, peanut protein hydrolysates are being researched for their potential bioactive roles in metabolic health. However, the presence of aflatoxin B1 remains a significant concern due to its carcinogenic nature.
According to a study published by "Journal of cellular physiology", the peanut, known as Arachis hypochaeus, contains the naturally occurring nutraceutical compound resveratrol. This specific compound is found in different fruits and nuts including the peanut. Resveratrol possesses several favorable biological and therapeutic activities.
