What to know about Ananas comosus (pineapple) before using it medicinally

Ananas comosus, commonly known as pineapple, is a nutrient-rich herb that has been widely studied for its health-enhancing properties, including its antioxidant, anti-inflammatory, and antimicrobial effects, which can help boost the immune system and reduce the risk of chronic diseases.

As a tropical plant, pineapple requires a subtropical climate with high humidity and well-draining soil, making it a challenging crop to cultivate in certain regions. Botanically speaking, the pineapple is a member of the bromeliad family, characterized by its tough, waxy leaves and a tough, fibrous stem that produces multiple flowers.

Historically, pineapple has been a prized fruit in many cultures, with ancient civilizations such as the Polynesians and Europeans using it as a food source and for medicinal purposes.

This article explains the medicinal, horticultural, botanical, and historical aspects of Ananas comosus.

What are the medicinal properties of Ananas comosus?

Ananas comosus helps with anti-inflammatory, antimicrobial, and antiseptic properties, treating conditions like arthritis, wound healing, and respiratory infections. It also has antioxidant and anti-cancer properties, reducing oxidative stress and inhibiting tumor growth. The fruit's juice and extracts are used in traditional medicine.

Bromelain, an enzyme complex, is the primary active constituent responsible for pineapple's medicinal properties. It also contains vitamins A and C, manganese, and other nutrients. Other key compounds include flavonoids, phenolic acids, and saponins, contributing to the plant's medicinal value. These compounds have been isolated and characterized.

The fruit, leaves, and stem of the plant are used for medicinal purposes. The fruit's juice is consumed for digestive issues and as an anti-inflammatory agent. The leaves are used to treat fever, coughs, and respiratory infections. The stem is used to treat wounds and skin conditions. The plant's parts are used individually or in combination.

Improper use of pineapple can cause side effects, including allergic reactions, gastrointestinal issues, and interactions with medications. The fruit's high fiber content can cause digestive discomfort, while excessive consumption can lead to kidney stone formation. Interactions with antacids, antihypertensives, and blood thinners are also possible.

Precautions when using pineapple medicinally include consuming the fruit in moderation, avoiding excessive consumption of the juice, and being aware of potential interactions with medications. It is also essential to consult with a healthcare professional before using pineapple extracts or supplements, especially for individuals with underlying medical conditions.

What are the horticulural aspects of Ananas comosus?

Ananas comosus grow in tropical and subtropical regions, requiring temperatures between 15-25°C and annual rainfall of 1000-2000mm. It thrives in well-drained soils with pH between 5.5-6.5. Adequate sunlight is essential, but protection from direct sunlight is necessary to prevent scorching.

To plant Ananas comosus, use fresh, not stored, crowns or slips, and plant them 10-15cm deep, with the crown exposed. Water regularly, and maintain soil humidity, reducing watering as the plant matures. Keep the area free from weeds to prevent competition.

For optimal harvesting, Ananas comosus should be picked when the leaves turn yellow and the fruit is mature, but still firm. Cut the pineapple from the plant using a sharp knife, leaving a small piece of stem attached to the fruit. Harvesting should be done carefully to avoid damaging the plant.

Common pests affecting Ananas comosus include scale insects, mealybugs, and fruit flies. Diseases like Panama disease (Fusarium oxysporum), crown rot (Fusarium moniliforme), and yellow spot disease (Mycosphaerella musicola) frequently affect the plant, leading to significant yield reduction and plant death.

What are the botanical aspects of Ananas comosus?

Ananas comosus is a perennial plant with tough, waxy leaves that are spirally arranged in a rosette shape. The leaves are dark green with sharp margins and contain a sap that is irritating to human skin. The plant produces a central stem with a crown of leaves.

Ananas comosus belongs to the family Bromeliaceae, order Poales, and class Liliopsida. The genus name Ananas is derived from the Tupi language, meaning "excellent fruit." The species name comosus refers to the plant's crown of leaves. The plant is native to South America but has been naturalized in many tropical regions.

There are several variants of Ananas comosus, including the Smooth Cayenne, Red Spanish, and MD-2. Smooth Cayenne is the most widely cultivated variety, accounting for 90% of global production. Red Spanish and MD-2 are grown in specific regions and have distinct flavor profiles.

Ananas comosus is native to the Americas, specifically in the tropical regions of Brazil, Paraguay, and Argentina. It has been naturalized in many tropical regions, including Hawaii, the Philippines, and Southeast Asia. The plant thrives in areas with high temperatures, high humidity, and well-drained soil.

The life cycle of Ananas comosus begins with a crown of leaves that grows into a flowering stalk. The plant produces multiple crowns, each of which develops into a single fruit. The fruit matures in 12-20 months, depending on the variety and growing conditions. The plant can produce multiple fruits throughout its lifetime, which can reach up to 20 years in ideal conditions.
