Health Benefits of Passion Fruit

Passion fruit's medicinal properties have been traditionally used to treat a wide range of health conditions. Nowadays, it is mainly consumed for:

  • Relieving stress and anxiety. Among the most important passion fruit's benefits is its relaxant effect, which helps soothe the nerves, reducing anxiety and controlling panic attacks.

  • Lowering blood pressure. In part due to its anxiolytic properties, passion fruit also provides hypotensive effects, which help maintain cardiovascular health.

Additionally, passion fruit can be helpful for improving digestion and bowel movements as well as for supporting bones health.

How It Works

The aerial parts of passion fruit have shown relaxant effects in low doses and sedative actions in higher doses. This is mainly due to the abundance of flavonoids; however, it is thought that other compounds may also be responsible for these nerve-soothing benefits.1,2 A group of beta-carboline alkaloids (harman, harmin, harmalin, harmol, and harmalol) have shown some influence over the central nervous system, and some studies suggest they may contribute to the calming and hypotensive effects of passion fruit.3,4

The combined action of the phenolic compounds, ascorbic acid, alkaloids, carotenoids, and flavonoids contained in the pulp of yellow passion fruit have proven effective in reducing systolic blood pressure.


Other herbs that promote relaxation and reduce anxiety are jasmine, lemon balm, and valerian, whereas lucuma and saffron help reduce blood pressure and support cardiovascular health.

Side Effects of Passion Fruit

When consumed in excess, passion fruit can also cause somnolence, and the latex present in the rind and other parts of the plant may trigger allergic reactions, including itching, rash, watery eyes and nose, and asthma.


The pulp of passion fruit contains cyanogenic glycosides, which are natural plant toxins present in several species. Unripe passion fruits contain the highest concentration of cyanide glycosides, losing most of their toxicity as they mature. When ingested, cyanogenic glycosides interact with digestive enzymes, releasing hydrogen cyanide, which is poisonous in significant amounts.

Early symptoms of cyanide poisoning include lightheadedness, giddiness, rapid breathing, nausea, vomiting, feeling of neck constriction and suffocation, confusion, restlessness, and anxiety.

When buying passion fruits, it is safer to pick the mature, wrinkled ones, which also release a strong, citrus odor and have a sweeter flavor.

People taking antihypertensive drugs, as well as those consuming sedatives and anxiolitics, must be aware that consuming passion fruit in excess or in remedial forms can potentiate the effects of those medications.

Additionally, people taking medications to prevent transplant rejection, such as tacrolimus or cyclosporine, are advised not to consume passion fruit.

Passion fruit is popular for its citrusy, sweet flavor, but it is also a good source of essential nutrients. Passion fruit juice provides generous amounts of vitamin C (ascorbic acid), which is necessary for boosting immunity, also aiding iron absorption for red blood production and healthy bones.

Additionally, passion fruit contains B group vitamins, mainly B3 (niacin), along with B2 (riboflavin), and small amounts of B6 (pyridoxine). B vitamins are essential for metabolic functions, such as proper protein and fat absorption, energy levels and eye health, as well as optimal nerve and brain function.

Moreover, this delicious, exotic fruit provides good amounts of potassium, which is crucial for blood pressure and electrolytes balance, making the passion fruit juice a great option after a sweaty workout session.

The nutritional value of passion fruit is rounded by adequate amounts of copper and pro-vitamin A.

Passion fruit is a tropical vine and requires a habitat similar to its native one to thrive. In warm areas, it can be successfully grown at home.

Growing Guidelines

  • Passion fruit vines are usually grown from seeds, but they can also be propagated from cuttings, which require hormone treatment and 90 days of rooting before being transplanted.

  • Passion fruit plants can thrive in most types of soils as long as they are well-drained, with a pH range of 6.5-7.5. If the soil is too acid, lime must be applied.

  • Passion fruit plants full sun exposure. However, when temperatures are too high, partial shade is also required.

  • For commercial purposes, the vines are trained to strongly-supported wire trellises at least seven feet (2.13 m) high. However, for home gardeners it is much easier letting the plant to climb a tall tree, which will also make it less prone to pests and diseases.

  • Regular watering will keep a vine flowering and fruiting almost continuously, and it is especially important when fruits are approaching maturity. Both water and nitrogen fertilization balance is key to developing high quality, flavorful fruits.

  • The passion fruit vine, especially the yellow variety, is fast-growing and will begin to bear fruits within one to three years.

  • In tropical areas, like Hawaii, passion fruits mature from June through January, with heaviest crops from July to August, as well as in October and November.

Prominent yellow cultivars include 'Yee Selection,' 'Noel's Special,' 'Hawaiiana,' and 'Mirim,' among others. Some of the most widely-cultivated purple cultivars are 'Bali Hai,' 'Ouropretano,' 'Common Purple,' and 'Brasilera rosada.'

Historical Information

Although passion fruit has most likely been grown for much longer, the earliest recordings of it are from the 16th century, when it was made known to the Western world via Spanish conquerors in Brazil. From there, it was taken to Europe before spreading throughout the rest of the globe. In 1880, it was introduced to Hawaii, where it adapted easily and eventually began growing wild.

Economic Data

Brazil currently produces the highest amounts of passion fruits in the world. However, they are grown in most places across the tropical belt, including other South American countries, Australia, and parts of Asia and Africa.

It is estimated that the total worldwide production of passion fruit each year is 852,000 tons. Brazil accounts for 90% of production, and the principle market is Europe, which imports more than 90% of the juice produced.
