What are heart seeds?

Balloon vine owes the name heart seed to its heart-shaped seeds. It is a plant that is actually native to the tropics and subtropics. It is a herbaceous, highly proliferating climber that can reach a growth height of up to 3.5 meters. However, it flowers when it is still quite a small plant and then forms airy balloon fruits up to 5cm in size that contain the plant's seed. Each of these black seeds is marked with a heart-shaped white spot, which gives the plant its name. Meanwhile, the plant has also become native to Germany and is regularly cultivated.

General and healing properties of heart seeds

The basic knowledge


Cardiospermum is anti-inflammatory. It is therefore a popular medicinal plant for non-infectious inflammations, as it soothes the inflammation and thus usually contributes to relief for the person being treated. Due to this cortisone-like effect, it is very popular for the treatment of rheumatic diseases and skin inflammations.


Heart seeds are anti-allergic. When the hay fever season approaches, it's back to inflamed sinuses and constant sniffles. The cortisone-like effect of the balloon vine stops inflammation and lowers histamine levels, so that the symptoms are drastically alleviated.


Cardiospermum is antipruritic. Inflammatory skin diseases such as psoriasis or neurodermatitis tend to itch terribly. The reason is a constant increased blood flow due to the latent inflammation of the skin. The balloon vine reduces the inflammation and thus also the itching.


The balloon plant is moisturizing. Inflamed skin areas tend to become brittle and cracked. They are an entry point for infections, they burn and hurt. Cardiospermum nourishes the skin and restores moisture and elasticity. The cracks can heal and the entry point is closed again.

Cardiospermum: Ingredients

The composition of the ingredients reflect the anti-inflammatory and antipruritic action of the plant. You can find the following ingredients in the heart seeds:
  • Triterpene saponins
  • Halicaric acid
  • Catechingerbstoffe

Heart seeds: Effect for body and mind

The herbal seeds are used in naturopathy for inflammatory, non-infectious diseases. Autoimmune is the keyword here and means that no bacterium, fungus or virus is responsible for the inflammatory event. So we are talking about diseases such as neurodermatitis, psoriasis, hives, acne, joint and soft tissue rheumatism, allergies and hay fever. Depending on where the inflammation takes place, ointments and creams or drops and tablets are used. Cardiospermum has been especially recommended for skin and mucous membrane issues, as it is good at relieving itching.

Fields of application in naturopathy

[Cardiospermum halicacabum.]
Its cortisone-like effect makes Cardiospermum interesting in the inflammations that do not have infection as a cause. The most common application is in skin diseases. Most often a cream or ointment is used. However, internal application as drops, tablets or spray is also common to use Cardiospermum in systemic processes.

Heart seed: Effect on inflammation

More generally, Cardiospermum is popularly used for non-infectious inflammation. Its anti-inflammatory effect is used to provide relief and alleviation for the patient. In this context, it is usually a component of mixtures that go in a similar direction.

Heart seeds for allergies

For allergies in acute phases Cardiospermum is a boon. Both in allergic eye inflammation and contact allergies of the skin Cardiospermum is the remedy of choice, because its anti-inflammatory and anti-allergic effect relieves the affected areas. They decongest and therefore no longer itch.

Heart seed: Effect on allergic skin diseases

Allergic skin diseases are usually accompanied by severe itching. One scratches the spot, breaks the skin barrier and opens the door for secondary infections. Since Cardiospermum is anti-inflammatory and thus itch-relieving, one no longer scratches at the wound, it can close and heal. The skin barrier is restored and the danger of a secondary infection is averted.

Heart seeds for rheumatism

In rheumatic diseases, an overactive, misdirected immune system is the problem. The body inflames some areas for no apparent reason or cause. Often affected are the fine, serous skins of the joints, the muscles but also the internal organs. Cardiospermum is anti-rheumatic due to its cortisone-like effect and can help to control the inflammation of rheumatism. It is usually used both internally and externally.

Heart seed: Effect for hay fever

During the acute phases of hay fever Cardiospermum is a boon. Hay fever is extremely unpleasant and massively affects the well-being, because the nose is constantly running and itching. Cardiospermum is often taken in such cases, because its anti-inflammatory effect relieves nasal mucous membranes. They swell, itch and drip no longer and hay fever loses its terror.

Heart seed: Effect on insect bites

Insect venom usually contains a lot of proteins and thus triggers strong allergic reactions in the skin or even systemically. The result is a burning, itching, throbbing and heated swelling. Since Cardiospermum has both an anti-allergic and anti-inflammatory effect, it is the first choice for such insect bites to get the unpleasant symptoms under control.

Heart seed for hives

Hives are also associated with allergic contact reactions. In hives, unpleasant, itchy water blisters form on the skin. Cardiospermum calms the inflammation of the skin, takes away the itching and allows the skin to reabsorb the liquid of the nettles.
