Formation and supply of blood bubbles

Blood bubbles are caused by excessive friction or mechanical pressure. For example, through too tight shoes or unusual work with a tool. The layers of skin lying on top of one another are separated from one another by the friction and the resulting cavity is filled with tissue fluid (“normal” bladder) or with blood. Smaller blisters can be treated with home remedies, but larger ones should be consulted with a doctor.

Piercing blood bubbles? What has to be considered

Bubbles in general, but also blood bubbles, encourage them to be pierced. If they are small, this can be done at home with the necessary caution. Larger blood bubbles should be in the hands of a doctor because the risk of infection is too great.

The needle used to open the blood bladder must be sterile. After piercing, the blood should drain completely. Then the wound is cleaned. Calendula essence is used for this - one or two teaspoons are mixed with a quarter liter of boiled, cooled water and the wound is rinsed with it. A compress soaked with this can also be applied for about 15 minutes. The calendula essence not only disinfects very well, but also contributes to healing.

After piercing the blood bladder, the wound must always be kept clean. Repeated washing or dabbing with the diluted Calendula essence is recommended. A pointed way tincture diluted with boiled water is also helpful.

The wound is best protected by a bandage that is not too tight. In the event of redness, swelling or even a general feeling of illness, a doctor must be consulted. If the wound is no longer open, it can be treated with a calendula ointment (calendula ointment).

Blisters on the foot or on the finger

Blood bubbles should definitely heal properly. Therefore pressure and friction must be prevented. Special blister plasters protect the area. The bladder cannot break open and ignite. Otherwise, the blood bubbles are supplied with special ointments, gels or tinctures.

Home remedies for open wounds

The open bladder wound can be dabbed several times a day with a sterile compress soaked in chamomile tea. The chamomile tea to be used for this is prepared from a tablespoon of flowers and half a liter of boiling water. After a brewing time of about 10 minutes, the tea is strained and can be used for the wound-healing compress once it has cooled down a bit. Chamomile has an anti-inflammatory, antibacterial, granulation-promoting and hemostatic effect.

An oak bark decoction is helpful in the acute phase. For this, a tablespoon of dried oak bark is mixed with a quarter liter of cold water, boiled for about 15 minutes and then strained. Oak bark is anti-inflammatory and antibacterial.

Yarrow is also recommended for wound healing. A teaspoon of dried herb is briefly boiled in 250 ml of water, gently squeezed out and wrapped in a sterile compress, placed on the affected area.

When the wound heals poorly

If the wound heals poorly, the following home remedies can help: Field horsetail tincture, marigold flower tincture and coneflower fluid extract are mixed equally. To treat the wound caused by the blood bladder, 30 drops of the mixture are mixed with half a glass of boiled water and the area is brushed several times a day.

An equally effective recipe consists of chamomile flower tincture, marigold flower tincture and yarrow tincture, mixed in equal parts. The application corresponds to the above. Mixture.

This tea recipe also supports the healing process: 20 g chamomile flowers, 20 g marigold flowers and 10 g ribwort herb. A tablespoon is poured over with half a liter of boiling water. After about 10 minutes, the tea is ready and only needs to cool down a bit before it is used for compresses.

Caution - no fatty substances on an open wound

Fatty substances such as ointments, curd cheese or creams have lost nothing on open wounds. The wound edges can be treated with anti-inflammatory ointments, but these are not to be found on open wounds. This hinders breathing and can lead to infection.

If the bladder is not open - home remedies

If the wound is no longer open or the bladder has not been opened, the following home remedies can help. All the ointments and gels mentioned here should be applied several times a day. A thick ointment bandage overnight supports the healing process.

Cooling helps with fresh blood bubbles in particular. This relieves the pain somewhat. The affected area is cooled with ice, wrapped in a washcloth, or an ice pack wrapped in a towel.

Aloe moisturizes, has a cooling and healing effect. Of course, the plant helps best here. An aloe leaf is slit open and supplies the blood bubbles with the escaping, gel-like substance - but who has an aloe plant at home? So usually a gel containing aloe has to be used.

What also works is the application of calendula ointment. Calendula is anti-inflammatory and stimulates the regeneration of healthy tissue. Ointments containing both calendula and echinacea (coneflower) are also recommended.

Manuka honey, which is cited again and again, is equally suitable for the treatment of blood blisters. This special honey supports wound healing.

If the blood bladder is still closed, an arnica ointment can be used to help. Arnica has an analgesic, anti-inflammatory and decongestant effect. However, arnica should never be put on open wounds.

Healing earth, a well-known home remedy, is also the right choice for blood blisters. This is mixed with water to a paste and then applied to the affected area. Once the earth has dried up, it is rinsed off. A porridge made from turmeric powder has a similar effect, mixed with a little honey.

Zinc ointment is usually used to heal wounds. This also helps with blood blisters.

Blood blisters in the mouth

Blood bubbles in the mouth initially look like little pimples. They can arise on the tongue as well as on the gums. Blood blisters in the mouth are caused by minor injuries, such as chewing hard bread. But allergic reactions to certain foods also cause these unpleasant, painful blisters. Another reason for this is the lack of vitamin B12 or vitamin C. Excessive alcohol or tobacco consumption can also lead to blood bubbles in the mouth.

As a rule, the small blood bubbles heal on their own. They should not be expressed as they may develop a secondary bacterial infection. The mouth should often be cleaned with suitable mouthwashes and oral hygiene should be taken seriously. Here, for example, rinsing with Ratanhia mouthwash helps. Ratanhia is anti-inflammatory and astringent. The Ratanhia root was already used by the Incas for oral and dental care.

Calendula essence is also helpful. Diluted with water, the mouth is rinsed out several times a day. Other home remedies are tea tree oil, which is used to dab the blood bubbles. We also recommend chamomile tea, which is used to rinse and dab at points. Last but not least, brushing with myrrh tincture has a pain-relieving and healing effect.

When to the doctor?

Large blood blisters, but also small blisters that cannot be treated with the help of the above-mentioned agents and / or are very painful, should be treated by a doctor.

Blood bubbles in the mouth, which are quite small, usually go away on their own. If there is pain and / or your own treatment does not work, you need to go to the dentist. This prescribes antibiotic mouthwashes and corticosteroids.

So that no blood bubbles form at all

To protect yourself from blood blisters on your feet, wearing silk socks under the actual socks helps. New shoes are rinsed with hot water and then put on, or rubbed with petroleum jelly before they are worn for the first time. It is best to rub the feet with baby powder - this protects against blisters. (sw)
