There are questions that arise in the days following a death that most people feel uncertain about asking — questions about what is actually happening to the body of the person they love, about the processes taking place behind closed doors, and about whether what is being done is something they should understand before giving their consent. Body embalming is one of those topics — a process that most families encounter in the context of funeral planning without having any real understanding of what it involves, what it does to the body, or whether it is the right choice for their situation. This comprehensive guide is written to change that. It covers the science, the step-by-step procedure, the chemicals involved, the alternatives, and the practical considerations that every family deserves to understand before making a decision about embalming for someone they love.

What Is Body Embalming?
Body embalming is the process of chemically treating a deceased person’s body to temporarily slow the natural decomposition process, restore a more lifelike appearance, and reduce the risk of disease transmission during the period between death and final disposition. It is performed by licensed funeral professionals — called embalmers — in a dedicated preparation room within the funeral home, using a combination of specialized equipment and chemical solutions designed to preserve the body’s tissues and present the deceased in a dignified condition for viewing.
The practice of preserving the dead is ancient — evidence of rudimentary embalming techniques has been found in cultures dating back thousands of years, most famously in ancient Egypt where mummification was practiced as part of a complex set of religious beliefs about death and the afterlife. Modern embalming as it is practiced in the United States today developed primarily during the Civil War era, when the need to transport soldiers’ bodies home across long distances made preservation a practical necessity. The techniques and chemical formulations have been refined significantly since then, but the fundamental goal remains the same: to preserve the body in a condition that allows for a dignified farewell.
Today, body embalming is practiced widely in the United States — more so than in most other countries, where refrigeration is often used as the primary means of short-term preservation. Understanding what it involves, what it does and does not accomplish, and when it is and is not the right choice gives families the information they need to make a genuinely informed decision rather than simply defaulting to whatever the funeral home suggests.
The Embalming Process — A Step by Step Walkthrough
The embalming process is more involved and more carefully managed than most people realize. Each step is performed with specific goals in mind — sanitation, preservation, and the restoration of a natural, peaceful appearance. Here is a detailed overview of what actually happens.
| Step | Description |
|---|---|
| 1. Preparation | The body is washed, disinfected, and positioned. Personal effects are cataloged and removed. |
| 2. Setting Features | Eyes and mouth are closed, facial features are set for a natural appearance. |
| 3. Arterial Embalming | A preservative solution is injected into the arteries, replacing blood and fluids. |
| 4. Cavity Embalming | Internal organs are treated with chemicals using a trocar to prevent decomposition. |
| 5. Final Touches | Incisions are closed, the body is washed again, dressed, and cosmetized for viewing. |
Step 1 — Initial Preparation and Disinfection
The process begins with the embalmer carefully washing the entire body with a germicidal soap designed to disinfect the skin surface and reduce the risk of disease transmission. The body is then positioned on the embalming table in the posture it will maintain for the viewing — typically lying on the back with the arms at the sides or folded across the abdomen. Personal effects including jewelry, clothing, and any medical devices are removed, cataloged, and set aside to be returned to the family or placed with the deceased as directed.
The embalmer conducts a thorough examination of the body at this stage — assessing its condition, noting any areas of discoloration, trauma, or decomposition that may require special treatment, and planning the embalming approach accordingly. The specific technique and chemical formulation used will be adjusted based on what is found during this examination. A body that has been refrigerated for several days requires a different approach than one that has been autopsied or one that has been affected by illness or trauma. This initial assessment is one of the most important steps in the entire process — the quality of the embalming depends significantly on the embalmer’s ability to read the condition of the body and respond appropriately.
Step 2 — Setting the Features
Before any chemical treatment begins, the embalmer works carefully to set the facial features in a natural, peaceful expression. This step is performed at the beginning of the process because once the embalming chemicals are introduced the tissues begin to firm, making adjustment more difficult.
The eyes are closed using small plastic caps called eye caps, which are placed beneath the eyelids to maintain their natural curvature and prevent them from sinking or opening during the viewing. The mouth is closed and the jaw is secured in a natural, slightly relaxed position using a variety of techniques depending on the embalmer’s training and preference — wire, sutures, or a specialized device called a mouth former may be used. The expression that results should convey peace and rest — a natural appearance that allows family members to feel that their loved one looks like themselves, at ease, and cared for.
Step 3 — Arterial Embalming
Arterial embalming is the central and most technically demanding step of the process. The embalmer makes a small incision — typically at the neck, near the carotid artery, or at another location depending on the condition of the body — and inserts a tube connected to an embalming machine. Through this tube, a preservative solution is pumped through the arterial system, pushing blood and natural fluids out of the body through a drainage point established at a nearby vein.
The preservative solution used in arterial embalming is typically formaldehyde based, diluted to the appropriate concentration for the specific body and condition. As the solution moves through the arterial system it penetrates the tissues surrounding the blood vessels, killing bacteria and halting the enzymatic processes responsible for decomposition. The skin begins to firm slightly, color is restored to areas of pallor or discoloration, and the overall appearance of the body improves significantly.
The arterial embalming process can take anywhere from one to several hours depending on the condition of the body and the degree of preservation required. The embalmer monitors the progress carefully throughout, adjusting pressure, flow rate, and chemical concentration as needed to achieve the desired result evenly throughout the body.
Step 4 — Cavity Embalming
Once arterial embalming is complete the embalmer turns attention to the body cavities — the thoracic cavity containing the heart and lungs and the abdominal cavity containing the digestive organs. These areas cannot be adequately reached by the arterial embalming process and require separate treatment.
Using a long hollow instrument called a trocar the embalmer punctures the abdominal wall and aspirates — removes by suction — the gases and fluids that have accumulated in the organs and cavities. A concentrated cavity fluid — typically containing a higher concentration of formaldehyde than the arterial solution — is then injected through the trocar into each cavity to preserve the organs and prevent the decomposition and gas production that would otherwise occur. The puncture site is then sealed with a small plastic device called a trocar button.
Step 5 — Final Preparation and Presentation
The final stage of body embalming focuses on presentation — ensuring that the deceased looks their best for the viewing and that the family’s experience of seeing their loved one is as peaceful and comforting as possible.
The body is washed a final time to remove any chemical residue from the skin surface. Any incisions made during the embalming process are sutured closed. The hair is washed and styled according to the family’s wishes or photographs provided. Cosmetics are applied to restore natural skin tone and color — this is a skilled art in itself, requiring the embalmer to match the deceased’s natural complexion and apply cosmetics in a way that looks natural rather than theatrical. The body is then dressed in the clothing chosen by the family and placed in the casket for viewing.
What Chemicals Are Used in Embalming?
The primary preservative chemical used in body embalming is formaldehyde — a colorless, strong-smelling chemical that kills bacteria and cross-links the proteins in body tissues, effectively halting the decomposition process. Formaldehyde is almost never used in its pure form in embalming — it is typically diluted in water to create a solution called formalin, which is then combined with other chemicals to create the specific arterial or cavity fluid used in the procedure.
Common additional chemicals used in embalming formulations include methanol, which acts as a preservative and solvent; glutaraldehyde, which provides additional tissue fixation; various surfactants and humectants that help the solution penetrate tissues evenly and maintain the natural texture and flexibility of the skin; and dyes that restore or enhance skin color. The exact formulation used varies by funeral home, by the specific condition of the body, and by the desired outcome — there is no single universal embalming formula.
It is worth knowing that formaldehyde is classified as a known human carcinogen by the International Agency for Research on Cancer. This classification is relevant primarily to funeral professionals who work with the chemical regularly — the exposure risk to family members and guests during a viewing is negligible. However it is one of the reasons that some families with environmental concerns choose alternatives to embalming such as refrigeration or more immediate disposition.
How Does Embalming Affect the Body?
The effects of body embalming on the physical condition of the deceased are significant and intentional. The replacement of natural fluids with preservative solutions temporarily halts the biological processes responsible for decomposition — the bacterial activity, the enzymatic breakdown of cellular structures, and the production of gases that characterize the natural return of the body to its elemental components.
The skin typically becomes somewhat firmer after embalming due to the protein cross-linking effect of formaldehyde. Color is restored to areas of pallor or discoloration — the face in particular often looks significantly more natural and peaceful after embalming than before. Facial features that may have relaxed or shifted after death are carefully restored to a natural resting position. The overall effect, when performed well by a skilled embalmer, is a body that looks peaceful, dignified, and recognizable — a version of the person that family members can approach without distress and spend time with during the viewing.
It is important to understand that embalming is a temporary preservation measure — not a permanent one. Even a well-embalmed body will eventually decompose once interred. Embalming buys days to weeks of preservation depending on environmental conditions and storage — it is not indefinite. The goal is to provide enough time for the family to hold a viewing, complete the funeral service, and arrange for final disposition, not to preserve the body permanently.
Is Embalming Required?
One of the most important things every family should know about body embalming is that it is not legally required in most circumstances in the United States. The Federal Trade Commission’s Funeral Rule specifically prohibits funeral homes from telling families that embalming is legally required when it is not — yet this misinformation is unfortunately still encountered by grieving families who are not aware of their rights.
There are specific circumstances in which embalming may be required or strongly recommended. These typically include situations where the body must be transported across state lines or internationally, where a significant amount of time will pass between death and the funeral service, where a public open-casket viewing is planned, or where specific state laws mandate it for certain conditions. In many other situations — including direct cremation, immediate burial, and home funerals where the body is kept refrigerated — embalming is entirely optional.
Some religious and cultural traditions actively prohibit embalming. Jewish tradition requires burial as soon as possible after death and generally does not permit embalming. Muslim tradition similarly emphasizes prompt burial without chemical treatment. Green or natural burial also typically excludes embalming, as the goal is to allow the body to return to the earth without chemical barriers. Families with specific religious, cultural, or environmental preferences should discuss these with their funeral provider before making any decisions.
Alternatives to Embalming
Families who choose not to have their loved one embalmed have several alternatives available depending on their timeline and disposition plans.
Refrigeration is the most common alternative to embalming for short-term preservation. Most funeral homes have refrigeration facilities that can safely preserve a body for several days without chemical treatment. For families planning a relatively prompt service this is often entirely sufficient and avoids the chemical exposure and cost associated with embalming.
Dry ice can be used as a preservation method in home funeral settings, placed beneath the body to slow decomposition without any chemical treatment. This is a common approach for families choosing home funerals who want to keep the body at home for a day or two before disposition.
Immediate or direct cremation eliminates the need for embalming entirely, as the body is cremated within a short time of death without a public viewing. Similarly, immediate burial — interment without a viewing — can proceed without embalming in most states.
Frequently Asked Questions
- How long does embalming preserve the body? Embalming can preserve a body for several days to a few weeks depending on the quality of the embalming, the environmental conditions, and how the body is stored. It is a temporary measure designed to allow time for viewing and funeral services rather than a permanent preservation solution.
- Does embalming hurt the body? Embalming is performed after death and does not cause pain or discomfort. The process does involve incisions and the introduction of chemicals into the body’s tissues, which means the body is altered from its natural state — something families should be aware of when considering the procedure.
- Can families view the body after embalming? Yes — this is one of the primary purposes of embalming. The process is specifically designed to restore a peaceful, natural appearance that allows family members to spend time with their loved one in a comfortable and dignified setting.
- How much does embalming cost? The cost of embalming varies by funeral home and geographic location but typically ranges from several hundred to over a thousand dollars. Under the FTC Funeral Rule funeral homes are required to provide itemized pricing — families should always ask for a complete price list and should never feel pressured to purchase embalming if they have not made an informed decision that it is right for their situation.
- Can I request to see the embalmer’s credentials? Yes. Embalmers are licensed professionals in every state, and families have every right to ask about the qualifications and licensure of the person performing the embalming. A reputable funeral home will have no hesitation providing this information.
- Is embalming environmentally harmful? The chemicals used in embalming — particularly formaldehyde — do enter the soil and water supply over time as the body decomposes after burial. This is one of the environmental concerns associated with conventional burial practices, and it is a consideration for families who are environmentally conscious and exploring alternatives such as green burial or water cremation.

Conclusion
Understanding what happens to the body during body embalming is not morbid curiosity — it is the kind of informed awareness that allows families to make genuinely free and genuinely right decisions for the people they love. Embalming is a significant procedure that alters the body chemically and physically, and families who consent to it deserve to understand what they are consenting to. They also deserve to know that it is optional in most circumstances, that alternatives exist, and that choosing not to embalm does not mean choosing a lesser farewell for their loved one.
The best farewell is the one that is most true to the person being honored and most supportive of the family doing the honoring. For some families embalming makes that possible — it provides the time and the presentation needed for a viewing that brings genuine comfort and closure. For others a different path serves better. What matters is that the decision is made with full information, without pressure, and in the light of the values and wishes of the family and the person they have lost.
