A Story from the Field: The Hundred-Drawer Cabinet That Smelled Wrong

Auntie Sri is sixty-two and runs the traditional medicine shop she inherited from her father, in a two-storey wooden shophouse not far from Phra Pathom Chedi in the center of Nakhon Pathom. The heart of the shop is an old teak medicine cabinet with almost a hundred small drawers, each labeled by hand with the name of an herb: green chiretta, turmeric, senna leaves, black ginger and the ingredients for many traditional formulas. The shelves hold glass jars of dried herbs, small bags of aromatic powder, herbal inhalers and balms that regular customers come back for every month.

When the flood came, the water inside the shop rose to about mid-shin. Auntie Sri and her son carried some of the jars and boxed products upstairs, but the cabinet was far too heavy to lift. The two lowest rows of drawers sat in water for several days, and every sack of herbs stored on the floor at the back got soaked. The shop was closed for almost three weeks.

On the first day back she opened the door and noticed a smell she had never known in forty years. The familiar scent of herbs was buried under a damp, musty odor mixed with mud. The bottom drawers had swollen so much they would not slide out. When she pried one open with a knife, the herbs inside had clumped together and were covered with white-green fuzz. Even some of the upper drawers, which the water never reached, had picked up a musty smell. A regular customer who came in for aromatic powder said, "Auntie, the shop doesn't smell the same anymore."

That night Auntie Sri sat looking at her father's cabinet and asked her son two questions. Could the herbs in the upper drawers, which still looked dry, be put out in the sun and sold? And how could they save the cabinet that had been part of the shop for her whole life?

Why an Herbal Shop Needs More Care Than an Ordinary Store

1. Herbs are swallowed and applied to the body. Dried herbs absorb moisture very readily. After several days in a damp room they grow mold easily, and some molds produce toxins that are invisible and are not removed by sun-drying or by any kind of treatment. Herbs that were touched by floodwater or that grew mold should never be sold or used again. This is the single most important point in this whole article.

2. Floodwater is contaminated water. The water that entered the shop carried whatever was in the drains, including bacteria that cause diarrhea and the organisms linked to leptospirosis. You cannot tell by looking whether something that sat in that water is clean.

3. Wooden cabinets hold moisture inside. Old wood that has been soaked stores water deep in its grain. If the drawers are closed and left alone, that moisture stays trapped, and mold spreads upward into the drawers above.

4. The health of the people in the shop and of customers. Many customers of traditional medicine shops are older people, some with chronic illnesses or allergies. Mold spores in the air can trigger coughing, sneezing and breathing difficulty.

5. A reputation built over decades. A traditional medicine shop survives on trust. If customers smell must or find mold in what they buy, a lifetime of trust can disappear in a single day.

What Many Shops Try That Should Be Avoided

• Sun-drying wet or moldy herbs and putting them back on sale: The sun makes them dry, but it does not make herbs that were contaminated by floodwater or mold safe. They should all be discarded.
• Ozone-treating the herbs to "rescue" the stock: Ozone treatment is for restoring rooms and surfaces. It is not a way to make contaminated herbs or medicines usable again. All herbs and medicines must be taken out of the room before treatment.
• Burning incense to cover the smell: It masks the odor for a moment, the smoke makes older people cough, and it does nothing to kill mold.
• Pouring bleach into the wooden drawers: The harsh fumes soak into the wood, can leave pale patches, and the chemical smell can transfer to the next batch of herbs.
• Closing the shop and running the air conditioner to dry it out: If the unit was exposed to damp or its filters are dirty, it can spread spores throughout the shop.

Before You Call the Team: Sort the Shop Clearly

Wear gloves, a mask and boots while you work. Make sure the electrical system is safe before using it. Then sort everything into the following groups.

• Discard everything in this group: Herbs and medicines that touched floodwater, herbs with visible mold, clumping or a musty smell, aromatic powder bags, balms, inhalers and ready-made products whose packets or boxes got wet, and sacks of herbs that were stored on the floor. Keep a written list of what you throw away as a record, and follow the guidance of the authority that regulates your shop.
• Move out and check later: Herbs and medicines from the upper shelves, in sealed containers, with no sign of damp or unusual smell. Move them to a dry place outside the room. If you are unsure about any item, follow the rule that throwing it away is better than taking a risk.
• Wash and keep: Glass jars, stone mortars, stainless steel trays and scales. Wash them with clean water and dish soap and let them dry completely.
• The wooden cabinet and drawers: Empty every drawer, take the drawers out, wipe off the mud, then leave the cabinet open and the drawers spread out so air can pass through until they are dry. Drawers that have warped or have mold deep in the wood may need a carpenter to repair or rebuild them.
• Grinders and electrical equipment: Herb grinders, bag sealers and the cash register should leave the room. If they were submerged, do not switch them on yourself. Have a technician check them first.

The Solution: WHD Disinfection and Ozone Treatment for Herbal Shops

Once all herbs and medicines have been moved out or discarded, the shop itself, the empty wooden cabinet, the shelving and the back storeroom need to be restored before any new stock arrives. World Health Disinfection (WHD) combines two main steps.

Disinfection service using CHEMGENE HLD4H disinfectant through an ultra-low-volume (ULV) fogger. The very fine droplets reach the gap behind the cabinet, under the counter and the wooden walls that sat in water, helping to reduce floodwater germs on surfaces.

Ozone treatment service. Ozone reaches into the empty cabinet frame and every open drawer space, helping to deal with mold spores in the air and on surfaces, and it breaks down musty odor molecules instead of masking them. The team uses a Master Ozone Generator, controlling dose and duration to suit the room size.

How the Work Is Done

1. Site survey: The team looks at the shop front, the medicine cabinet, the storeroom, the upper floor, areas where mold has appeared and how high the water reached.
2. Preparation check: The team confirms that every herb, medicine and package has been moved out or discarded, that electronics and rubber items have been moved out or fully covered, and gives advice on clearing mud.
3. Disinfection fogging: Fine mist is applied through the empty shop, covering floors, walls, the counter, shelving and the cabinet frame.
4. Ozone shock treatment: The shop is sealed with no people, pets or plants inside, and time and concentration are controlled.
5. Ventilation: Doors and windows are opened until the ozone has broken down back into oxygen, and the wooden cabinet is left to dry further before any new stock comes in.
6. Re-check: The team checks for smell and the dampness of the wood again, and gives advice on storing herbs over the long term.

Ozone safety: No people, pets or plants may be in the room during treatment, and the room must be ventilated until the ozone smell is gone before anyone goes back in. In an herbal shop, no herbs, medicines or packaging of any kind may remain in the room. Electronics and rubber items must be moved out or covered, and the team uses a controlled ozone dose.

10 Reasons a Traditional Medicine Shop Should Restore Its Premises Properly

1. The scent of herbs returns: Once ozone treatment has broken down the musty odor, the aroma of new stock is no longer buried.
2. A cleaner empty cabinet: Fewer spores in the frame before new herbs go in.
3. Cleaner surfaces: The counter, shelves and floor have been through disinfection fogging, reducing floodwater germs.
4. Reaches places a cloth cannot: Behind the cabinet, under the counter and the corners of the wooden ceiling.
5. Looks after older customers: Cleaner air in the shop means fewer allergy triggers.
6. No chemical smell left in the wood: CHEMGENE HLD4H does not have the harsh fumes of bleach.
7. Easy daily cleaning: Use the disinfectant spray on the counter as directed on the label.
8. Keeps customer trust: A clean shop, fresh stock and no musty smell.
9. Reopen on schedule: A clear process tells you when the shop is ready for new stock.
10. Ongoing advice: If the smell or damp returns, contact the team by LINE or phone.

Before and After Restoring the Shop

Storing New Herbs So Mold Does Not Return

• Use airtight containers: Glass jars or boxes with tight lids, labeled with the herb name and the date received.
• Buy what you can sell: Do not hold stock longer than needed, and use first in, first out.
• Keep everything off the floor: Never put sacks or boxes directly on the floor. Use shelves or pallets.
• Open the drawers to air them regularly: And watch for any unusual smell or marks.
• Put a hygrometer in the shop: So you know quickly when the air becomes unusually humid.
• Clean the air conditioner filters: A clean unit helps control humidity and does not spread spores.
• Watch the walls after heavy rain: If you see new damp patches, deal with the cause before mold spreads.

If the shop has upholstered chairs or a waiting corner for customers, the dust mite removal service can be added. You can also read more about ozone odor and chemical residue removal.

Bringing an Old Wooden Medicine Cabinet Back to Life

An old medicine cabinet is the heritage of the shop, and many owners want to keep it if at all possible. The best approach is to take out every drawer, wipe away the mud with a damp cloth and clean water, then stand the drawers on their sides in a shaded place with good airflow. Avoid strong direct sun, because old wood can crack if it dries too quickly. Once the wood is properly dry, a carpenter can plane or sand away mold stains on the drawer surfaces and repair drawers that have swollen out of shape.

Disinfection fogging and ozone treatment are carried out while the cabinet is empty and the drawers are laid out in the room, so the ozone can reach both the frame and each individual drawer. After ventilation, wait until the wood is completely dry and free of any musty smell before filling it with new herbs. If a drawer still smells, repair or replace it. Never put herbs into a drawer that still smells musty.

Many owners find that the cabinet, once dried and treated, smells of clean wood again within a few weeks. Taking photographs before and after the repairs is also a good idea. It records the history of the shop and reassures long-standing customers that the cabinet they remember is still there and has been cared for properly.

A Step-by-Step Plan to Reopen

Most traditional medicine shops are family businesses, often run by an older owner with help from a son or daughter. A simple plan helps the family work through the recovery without feeling overwhelmed.

Days 1 to 2, safety and sorting. Have the electrics checked. Separate everything that touched floodwater or shows mold and set it aside for disposal. Move the sealed, unaffected stock to a dry place. Photograph the damage for your records and for any insurance or assistance claims.

Days 3 to 5, clearing and drying. Dispose of contaminated herbs and products, take out all the drawers, wash mud from the floor and the lower walls, and leave the doors and windows open during the day so the wood can start drying.

Days 6 to 7, room treatment. With the shop empty of herbs and medicines, the WHD team carries out disinfection fogging and ozone treatment, followed by full ventilation.

Day 8 onward, careful restocking. Wait until the cabinet and drawers are fully dry and smell clean. Arrange repairs for any damaged drawers. Then order fresh herbs in quantities you can sell, store them in sealed containers, and reopen to customers.

Telling regular customers about the plan, even with a simple handwritten sign on the door, helps them understand why the shop is closed and reassures them that you are putting their health first.

Talking to Customers About Discarded Stock

Throwing away a large part of the stock is painful, especially for a family business. It can feel tempting to keep herbs that "look fine." But explaining the decision to customers can actually strengthen the shop's reputation.

Many long-standing customers will understand immediately if you tell them that every herb that touched floodwater has been discarded and that all the stock on the shelves is new. Older customers in particular often remember earlier floods and appreciate a shopkeeper who does not cut corners. A short note at the counter, or simply mentioning it when customers ask how the shop came through the flood, is enough.

Keep the list of discarded items you made when sorting the shop. It helps with any insurance or assistance claims, and it also helps you decide which herbs to reorder first based on what your customers ask for most often.

What to Watch in the First Month After Reopening

The weeks after reopening are when hidden damp tends to reveal itself, especially in an old wooden shophouse where the walls and floor may have absorbed more water than they appear to have done.

Check the lowest drawers every few days. Even after repair, the bottom rows of the cabinet sit closest to the floor. Open them, smell them and look at the corners. If any drawer starts to smell musty again, empty it immediately and let it air out before using it.

Look at the jars and labels. Condensation on the inside of a jar, or paper labels that curl or show spots, are early signs that the air in the shop is still too humid. Move the jar to a higher, drier shelf and check the hygrometer reading.

Notice how customers react. Regular customers are often the first to say whether the shop smells right. If anyone mentions a musty smell, take it seriously and look for the source rather than covering it up.

Keep the doors open when you can. On dry days, open the front of the shop for a few hours to let fresh air move through. Close up again before evening when humidity rises.

If the smell returns despite these steps, contact the team. A follow-up check is much easier to arrange early than after mold has spread through a new batch of stock.

Customer Voice (Example Scenario)

"At first I hated the idea of throwing the herbs away. I wanted to dry them in the sun and keep selling them. The team explained that anything that had been in the water or grown mold had to go, and had us move everything out of the shop before they disinfected and used ozone. My father's cabinet doesn't smell musty anymore, and customers walk in and smell the herbs the way they always did."

— Auntie Sri, traditional medicine shop owner, Mueang Nakhon Pathom (example scenario from the field)

Frequently Asked Questions

Q: Herbs that were in the flood have now been dried in the sun. Can they be sold?
A: They should not be sold or used. Herbs that touched floodwater or grew mold should all be discarded, because sun-drying does not remove floodwater germs or mold toxins.

Q: Can ozone make moldy herbs usable again?
A: No. Ozone treatment is for restoring rooms and surfaces. All herbs, medicines and packaging must be moved out or discarded before treatment.

Q: Can an old wooden cabinet be saved?
A: Usually yes, if the frame is still sound. Remove the drawers, let everything dry, and have the empty cabinet disinfected and ozone-treated. Drawers that have warped or have mold deep in the wood should be repaired or rebuilt by a carpenter.

Q: How long will the shop need to close?
A: It depends on the size of the shop and how wet the wood is. The team gives an estimate during the survey and recommends waiting until the cabinet is completely dry before taking in new stock.

Q: Do herbs on the upper shelves that never got wet need to be thrown away too?
A: If they were in sealed containers and show no unusual smell or marks, they may be kept, but they must leave the room during the work. If you are unsure, it is better to discard them than to take a risk.

Q: Which areas do you cover?
A: Mueang Nakhon Pathom, Nakhon Chai Si, Sam Phran, Kamphaeng Saen, Bang Len and nearby areas. Ask about available dates by phone or LINE.
