Među darovima prirode, kojima ninsko područje obiluje, sigurno je jedan od najvrjednijih ljekovito blato koje se nalazi u blizini znamenite duge pješčane Kraljičine plaže. Njegovu su djelotvornost provjerili deseci tisuća ljudi koji, u organizaciji i uz nadzor zdravstvene ustanove iz Zadra, već četiri desetljeća blato koriste za liječenje raznih tegoba kao što su reumatske bolesti, deformacija kralježnice, problemi lokomotornog sustava, ženska neplodnost i razna kožna oboljenja.
Blato:
To je mješavina suhe i tekuće tvari. Blato čini sitnozrni sediment, zasićen vodom, na dnu vodom prekrivenih površina (rijeke, mora, jezera, oceani). Predstavlja početni stadij u nastajanju brojnih sedimentnih stijena. Kad je navlažen u tekućem je stanju, kada se osuši prelazi u čvrsto stanje. Ime ljekovito blato dolazi zbog sastojaka vapnenačkog mulja na lokaciji, a to su peloidi. Osnovna podijela peloida je prema nastanku: prirodni i umjetni.
Prirodni peloidi su produkti mineralne vode(slatke ili slane) pomiješane s organskim i anorganskim česticama koji nastaju geološkim i biološkim procesima, a koriste se u terapeutske, odnosno medicinske svrhe, a umjetni se dobivaju preradom prirodnih kako bi se mogli koristiti izvan lječilišta. Prirodni ljekoviti činitelj kao što je peloid, uz sunce, more i čisti zrak, povoljno djeluje na očuvanje i unaprjeđenje zdravlja, poboljšanje kakvoće života, te na sprečavanje i liječenje različitih bolesti te na oporavak od istih.
Ljekovita blata, spominju se od početka same ljudske vrste. Smatra se da su čak i neki preci današnjeg čovjeka, poput Homo Erectusa i Homo Neandertalensisa, koristili smjesu vode i mulja za liječenje raznih kožnih problema.
Postanak je geološkog ili biološkog podrijetla, često s velikom količinom organske materije (mikroorganizmi, alge, bakterije), sa stalnim izmjenama, odnosno kemijskim i fizičkim promjenama.
Sedimentološki gledano peloide ubrajamo u vapnenačke materijale.
Vapnenci se sastoje od skeletnih i neskeletnih čestica.
Skeletne čestice obuhvaćaju skelete organizama čije su ljušture građene od karbonatnih minerala, a tu ubrajamo:
- Mekušce - školjkaši, puževi i glavonošci
- Ramenonošce
- Koralje
- Bodljikaše - krinoidi i ježinci
- Mahovnjake
- Planktonske i bentičke foraminifere
- Alge - crvene, zelene, žutozelene i modrozelene /cijanobakterije
Neskeletne čestice dijele se na:
- obavijena zrna
- peloide
- agregirana zrna
- intraklaste
Pojam peloida odnosi se na kuglasta, elipsoidna, valjkasta ili vretenasta karbonatna zrna, čija je veličina najčešće između 0,1 i 0,5 mm, no mogu doseći i nekoliko milimetara.
Takvi muljevi često nazivaju ljekovitim blatom jer se smatra da neki od njih, nastali u posebnim uvjetima pri visokim temperaturama i tlakom, uz manjak kisika, imaju ljekovita svojstva, prvenstveno za kožu i kosti, ali preporučuju se i kod bolesti probavnog trakta, nakon operativnog zahvata na reproduktivnim i mokraćnim organima, kod olakšavanja respiratornih bolesti te smanjenja tjelesne otpornosti. U ljekovite svrhe takvi se muljevi miješaju s vodom te takvom smjesom prekrivamo tijelo u određenom vremenskom periodu i na određenoj temperaturi.
Kako su se razvijale različite definicije peloida, tako se mijenjala i njihova klasifikacija, pa između ostalih postoje:
- Primarne i sekundarne peloide:
- primarni peloidi je onaj čiji kruti dio biva prenesen vodom u suspenziji i istaložen u mineralnoj vodi
- sekundarni peloid je onaj čija je tekuća faza različitog podrijetla od krute faze.
- Filo-peloide, organo-peloide i sulfo-peloide:
- Filo-peloidi su oni u kojima su filosilikati glavni sastojak
- Organo-peloidi u kojima je glavni sastojak organska tvar
- Sulfo-peloidi u kojima je prirodni sumpor ili sulfidi/sulfati glavni sastojak.
- Medicinski i kozmetički peloidi:
- Medicinski peloidi su oni koji su istraženi od laboratorija i osoba čije područje rada je medicinska hidrologija i fizioterapija, a koji određuju dozvoljene količine određenih sastojaka u medicinske svrhe
- Kozmetički peloidi su oni koji imaju određene kozmetičke koristi prepoznate od laboratorija koji se bave dermatološkim problemima.
Važno je napomenuti da su peloidi „živući sistem“ u stalnim promjenama. Njihov terapeutski učinak ne dobiva se samo od originalnih sastojaka (krute i tekuće faze), nego i teksturnih, fizikalno-kemijskih i bioloških promjena koji se dešavaju tijekom procesa miješanja i promjena unutar samog sedimenta.

Among the gifts of nature, which the Nin area abounds in, surely one of the most valuable is the medicinal mud located near the famous long sandy Kraljičina beach. Its effectiveness has been tested by tens of thousands of people who, in the organization and under the supervision of a health institution from Zadar, have been using mud for four decades to treat various ailments such as rheumatic diseases, spinal deformity, locomotor system problems, female infertility and various skin diseases.
Mud:
That is a mixture of dry and wet matter. It is composed of small grain sediment, saturated with water, on the bottom of areas covered by water (rivers, seas, lakes, oceans). It represents the initial stage in the formation of numerous sediment rocks. When moist, it is in liquid shape, and when dry it becomes solid. It is called healing mud, because of the ingridients of limestone mud on a location, called peloids. Basic classification is by formation: natural and artificial peloids.
The natural peloids are products of mineral water (salt or fresh) mixed with organic and unorganic particles which were formed in geological and biological processes. They are used in therapeutic and medical purposes. The artificial peloids are produced from natural peloids with the purpose of being used in other places. Along with sun, sea and clean air, the natural healing factor as is a peloid, has a positive effect on the preservance and improvement of health, quality of life, and prevention and treatment of various diseases and recovery.
The healing muds are mentioned from the start of the human race. It is thought that some of the ancesters of today's Homo Sapiens, like Homo Erectus and Homo Neandertalensis, were using a mixture of water and mud for treatment of various skin problems.
The origin of mud is geological or biological, often with a large quantity of organic materials (such as microorganismes, algae, bacteria), with constant modifications or chemical and physical changes.
Sedimentologically speaking, the peloids are numbered among limestone materials. The limestones are composed of skeletal and nonskeletal particles. The skeletal particles contain the skellets from organisms whose shells are made of carbonate minerals:
- Molluscs - bivalves, gastropods and cephalopods
- Brachiopods
- Corals
- Echinoderms
- Bryozoans
- Plancton and benthic foraminifera
- Algae - red, green, yellow-green and blue-green /cyanobacteria
The nonskeletal particles are:
- coated grains
- peloids
- aggregated grains
- intraclasts.
The term „peloid“ refers to spherical, ellipsoidal, cylindrical or spindle-carbonate grains, ranging from 0,1 to 0,5 mm, but they can reach several milimeters as well.
Such mud is often called „healing mud“ because it is considered that some, which was formed under special conditions at high temperatures and pressure, with a deprivation of oxygen, has healing properties, mainly for skin and bones, but it is also recommended for diseases of the gastrointestinal tract, after surgery of reproductive and urinary organs, alleviating respiratory diseases, and in cases of reduced body resistance. For the purposes of healing such mud is mixed with water and used to cover the body at a specific temperature in a specific time period.
As different definitions of peloids developed, so changed their classification. Among others exist:
- Primary and secondary peloids:
- primary peloids are those whose solid part was transfered by water in suspension and precipitated in mineral water
- secondary peloids are those whose liquid phase has a different origin than solid phase
- Filo-peloids, organic-peloids and sulpho-peloids:
- Filo-peloids are those in which the main ingridient is phyllosilicates
- Organic peloids are those in which the main ingridient is organic material element
- Sulpho-peloids are those in which the main ingridient is natural sulphur or sulfides/sulfates
- Medical and cosmetic peloids:
- Medical peloids are those that have been explored by a laboratory and persons whose area of expertise is medical hydrology and physical therapy, and who determine the permitted amounts of certain ingridients for medical purposes.
- Cosmetic peloids are those that have certain cosmetic benefits recognized by a laboratory which is dealing with dermatological issues.
It is important to mention that peloids are „living systems“ in constant changes. Their therapeutic effect is obtained not only from original ingredients (solid and liquid phase), but from textural, physical,chemical and biological changes which are occuring during the mixing procces and changes within sediment itself.
